I have a 67 with stock interior, seats and lap belts. I like those 4 point belts/harnesses that are out there, but they all seem to attach to a roll cage. Is it possible to custom fab a bracket from the floor to attach to, or do they make a belt/harness similar to what I am looking for??

This is something similar to what I want minus the crotch belt, so it will be somewhat comfortable and safe on the street. I think the biggest issue may be folding the seat forward or moving it excessively. Thanks for any help!!

You can do like I did and cross the uppers behind the back of the seat and use the stock mounting points. (You'll need to buy longer hardened bolts.)

The seats came with the car. (I was told they were out of a Vette.) I added the belt holders from a 70-74 Camaro to both sides to keep the belts in place.

Thats perfect, thanks for the post and pics!!... I think the hardest part will be finding the clips and mounting them to the seat to hold up the belts. How did yours mount?

Dude, that cant be safe!!

Every seatbelt guy i've talked to says that idea for the shoulder harness's is a horrible idea.

My logic is that it would be more safe then just the 'ol lap belts that I have currently!! Anyone else have any thoughts?

At that angle, a front on collision, those belts will compress your spine so flipping bad you could be paralyzed.

Jg95z28 the belts do look great in your car !! But i will have too agree with Max that they are not installed in a safe way for the belts too give you full protection,,they will slip right over your shoulder the way you have them,,i say this knowning a good friend was killed in a dirt track car due to the belts being installed something like you have yours,I have just been talking with Kevin W about getting up the stuff too make up me a set of factory type shoulder belts,,Shoulder harnesses are a great idea only if there used right and i think they should both pull stright up by the neck and then anchored in the center not on both sides ,,,Just my opinion, Frank

What about not crossing the shoulder harness behind the seat as shown but bolting them in on their respective sides. Some also have the single strap that mounts to the floor/cage, maybe I could fab up a mount with some grade 8 hardware??

I thought about the same thing, and it was still not safe enough.

Look at this link.

Nrmedic984 glad too see you didnt take it wrong when we told you that your belts are UNSAFE,,I really like the seats you have in your car are yes there out of a vette,, If I was you I would be looking to getting a set of factory type shoulder belts ,,Try to contact Kevin W,, he can give you all the info on the factory belts,,,,Frank

So pretty much there is no safe way of installing a 4 point without a roll cage tube to fasten it to that crosses high behind the headrest? Maybe it'll just be the lapbelts for now, but after seeing a few high speed crashes, I am hoping to get something better. Where can I find Kevin? Thanks

Nrmedic984 look at this thread you will find Kevin W in it http://www.camaros.net/forums/showthread.php?t=55488,, Ricks does offer a aftermarket set of shoulder belts ,, they just look like later model belts,but they work great. Frank

Sorry, but I don't do 4 points :) and for a coupe, the shoulder mounting point is already there. Maybe you can mount a bar along the headliner attached at the factory shoulder belt mounting holes, then attach the upper points to the bar. That would give you a 4 point and at the correct higher than the shoulder mounting point. Just my .02

Kevin, that's what we did in my dad's vette, it worked out great.

The only problem is if the back seat will ever get any use in this case. I guess you could unbolt it and only use the lap belts if it's a rare occasion.

Excellent, thanks for all the info everyone. I do like the 4 point harness better, but safety is the goal. I'm kinda leaning towards the ones in Summit that state "floor mounting", but havent been able to find the installation instructions. Most people here seem to be against the floor mount harnesses, for obvious safety reasons. I'll have to call the manufacturers to see how they are suppose to floor mount... Thanks again1

Most harness type belts are made too go thru the middle of the seat and then to the anchoring point,, Just tell the vendor what kind of seats you have so they will understand how they are mounting in the car,,Take a look at the SB-69 that ricks sells http://www.rickscamaros.com/cgi-local/SoftCart.exe/online-store/scstore/catalog_carpet.htm?L+scstore+szxp1176ffab4fab+1112 892841 then click on replacment belts on the left,,,,Frank

I decided to go with a RJS 5 point for $75 each that are floor mount and meet SFI specs. I called them direct and they were very helpful. They should be here by monday, and I'll let everyone know how they worked out. Thanks everyone for all the help, ideas and advice.

FWIW. Is it as safe as a true 4-point set up? Certainly not. But it is much safer than the standard lap belts alone. Once you're latched in and the tension tightened, your shoulders will not slip out as someone else suggested. The retainers are stock 70-74 Camaro units which I fastened to the seat. (Both sides.) It was done more for looks in the first place. My son and I built this car together and he wanted that look. Once he's off to college in the fall it becomes my car again, and then I'll be looking to replace the seats with stock ones... if I can find them, as the car was equipped with deluxe buckets with headrests.

Lastly, I am an engineer by trade, and if I thought this set-up wasn't safe, there's no way in hell I'd let my kid drive the car.

Jeff G- That's pretty much my goal also - to make it safer than only having lap belts. I would take your setup anyday versus "lap belts only" and a mouthful of steering wheel/column....

Those are some sweet seats what year corvette? And do you have any more pictures of them in your car? :)

To be honest I'm beginning to think the guy who sold me the car was full of it. I can't find any manufacturer marks or numbers on the seats, nor do they look like they ever actually came in a Vette. I'm thinking of replacing them with stock buckets in the near future.

Here are a couple pictures from when I bought the car:

This months Car Craft has a very short article on three point belts (like modern cars have) for First Gen Camaros that appear to use the stock mounting points. The cost something alike $350 or so. Cheap insurance and they are comfortable looking. If you are interested I will get you the information.

Has anyone tried the belts that Rick's sells?

I whould read this http://www.sparcousa.com/resourceFiles/16.pdf

How about if you mount the harness to a belt mounted at the rear shelf above the rear seat?

Kevin, is this what you had in mind. They call them harness bars http://www.sparcousa.com/harness_bars.asp
You could brobably make it removeable (for track days)

I was thinking about mounting a harness to the shelf above the rear seat, but i didnt know if it would be strong enough. That harness bar looks cool if you could find a way to make it easy to bolt up and take in and out.
Here is another site that gives some recommendations for mounting harnesses.

Yea, they don't make one for a 1st gen Camaro.
I found a site from the DOT about seat belt mounting angle, but I can't find it.

As far as the shelf not being strong enough, you'd probably have to reinforce it somehow.

This isn't an option if you want to use the rear seat on a regular basis. But you can mount the rear harness straps, to where the rear seat belts bolt in.

Actually I think the ones mentioned in Car Craft are the ones Rick's sells for $299.99.

Mounting the seatbelts to the floor with a shoulder harness is a bad idea. Create an arc from the pivot point (Mounting point) and that is the movement the belt will allow. In a front impact, you would move forward and the belt would be pulling you forward and down, breaking your shoulder blades in the process. I have a 68 convert and added a three point retractor system using the original mounting location. The third point was mounted on the flat surface by the rear 1/4 window. I increased the metal thickness locally. If ever I wished to revert back to original. I just have to replace the rear 1/4 trim. I know the 4 or 5 point systems look cooler, but this is a much safer option. Remember we have a frame w/o crush zones so WE absorb a lot of the impact. Hope this helps.

Not purposely steering this the wrong way, as this is fascinating, but I have seen some modern OE seats with the harness built in (probably in convertible applications). Has anyone ever seen anything like this, and more importantly, seen a setup like this installed in a retro application like a Camaro?

How about rear 3-point setups? Kids will sit back there, you know.

I have also been told race-type harnesses are illegal on the streets because it is harder for rescue workers to get you out. Has anyone ever heard of that? (inspected cars, I might guess; in NJ, with the right registration, no inspection on old cars)

Before I installed my 3 point set up in my convert, I purchased a set of 2001 Sebring convert seats with the built in belts as mentioned earlier. When the car is viewed from the front, the seats looked out of place. With the top down the seat top is as high as the windshield header. This seat would work fine, but I didn't like the look.

What about some late model "take-offs" from a 4th gen F body? I wouldn't suggest using some from a wrecked car b/c of the possibility the belts were in use at the time of the accident. I like this idea myself for updating the look of the interior and safety of the car by using someting from an OEM rather than aftermarket. It just seems that the quality might be better. Plus, you can get a matching set for front and rear. I haven't looked at the F body rears before, but they may even be the three point style mentioned before? Of course, that would require some modification to the rear seat package tray-perhaps with a steel plate or cross bar mounted under the package tray from inside the trunk???
