Methods for attaching RS Fender Adapters

I'm finally moving along with my RS front end conversion, and I'm curious about those people who have added an RS grill and used the tabbed fender adapters that allow you to mount the motorized buckets properly. I'm using the Camaro Central Stage 3 Kit, where the entire bucket/headlight assembly comes all set up and pre-tested... all you do is mount the bucket, connect the module & wires, and its supposed to work.

But the question I have is all about the adapters... the existing fender tabs are factory spot-welded, and the new brackets have matching tabs that align and nest with the existing fender contour. Different people have suggested different methods:

1. Just bolt the tabs together with a pan-head SS machine screw, a couple of washers, and a nylon lock nut.

2. Spot/Tack Weld all three tabs which is probably OK for a project in works car.

3. Use 3M Panel Bond on the tab mating surfaces after sanding off the paint, and then bolt or rivet the bracket to the fender.

In the case of #3, some people have sanded inside the fender "nose" and also bonded the entire 7 or 8 inches although there's nothing clamping the two pieces other than maybe a couple of temporary clamps until it cures.

So what have YOU done? What is overkill, and do you think just bolting it together with locknuts is sufficient? I read that article from Super Chevy when they did the conversion with this kit and they just bolted it together. After all, most of the car is just bolted together LOL. Pardon the extra long 8-32's in the pictures... I just grabbed what was handy as they don't include screws with the kit.

Hey John... Have you used rivets with these brackets? Just curious bc the diameter of the bracket holes is larger than the OEM fender tab holes so if I used machine screws a washer is necessary.

All I've got is a pop-rivet tool, would that work with a washer, kind of like a small fender washer? Or do I need some exotic rivet tool for these six spots?

Which method did you use and why?

I haven't done mine yet, but my plan was to use 3M panel bond adhesive on the sides, inside the fender. I'm impressed with this stuff. I used it previously and was thoroughly impressed with its strength.

Just a heads-Up Donny... don't permanently attach them until you have fitted them completely with the grill in place after you get them working. I put the 2nd bucket in this afternoon and then unpacked the grill to see how it would fit. It didn't LOL. I think I'm going to go at this a little different. Maybe pull both buckets out and see what the grill fits like. I already know there's a interference spot on the extreme corner of the upper PS valance where the fender connects... I'm going to have to grind down the raised edge to get rid of the interference. Also, I'm going to to set the buckets back a little more by elongating the lower tab holes because the grill is hitting the outside passenger side of the bucket frame. Might be able to tweak the grill a little before paint... and paint is the last thing on my mind right now. I already used a step drill to open up the two bucket locator holes on the radiator support wall. Did that to allow some jiggle in aligning the bucket, will use fender washers to lock it up when I find the sweet spot.

One last thing I'll share... is page 3 of the instructions in its entirety LOL.

Re: Methods for attaching RS Fender Adapters

Dave... The instructions as many other have said... leave a lot to be desired. They do tell you to read the Super Chevy article, which has some pictures but not a whole lot about the details of the install. But when I saw that page I literally groaned and then started laughing.

I will say that the pre-assembled and tested buckets are really nicely made. And as far as the install, we'll I guess that's why that page was in the box. There's going to be a lot of tweaking, but eventually it'll work out. I hope!

Re: Methods for attaching RS Fender Adapters

So I pulled both buckets today, also the brackets, trying to test fit the grill shell. Still have the high spot mentioned earlier where the 4th tab is just under the header where the stiffener nests. I'll deal with that later. pushing in as much as I could/dared (and I don't want to stress the part) the "V" in the center is out about 1/2" so I decided to compare new and old.

Laid them on my pool table and weighed down the opposite end so that both flanges were dead even. Went over and measured the difference at the opposite end... its a good healthy half an inch, maybe 5/8". So maybe this piece came out of the mold warm and didn't cool off at the exact angle. I know some guys have used heat guns to alter the contours of the flanges on these '69 grills, but I'm wondering if I should attempt to heat up the center a little and gently push on it to see if I can "spread" the grill a little so there's no stress on it when its bolted to the lower valance?

Did you buy a repop grille or a GM part? The original grille is still available from GM.

Re: Methods for attaching RS Fender Adapters

I used sheet metal screws to fasten them and then bent, shimmed with washers as needed. The screws never came loose and nothing ever moved after being fit to there they needed to be and then screwed tight.

Donnie... Are you talking about the buckets or the grill? If its the buckets, I'm thinking its best to start with the two rear bucket bolts, space the bucket out about 1/2" and since the holes are oversized and fender washers are on both sides of the bulkhead, you should be able to move the buckets to fit the grill opening once you get the grill to seat properly. I'm attaching a picture of what one guy did to space the buckets, used oversized bolts as a spacer. Weird, but he claims it worked.

Re: Methods for attaching RS Fender Adapters

Been pulling my hair out for a week trying to get the RS buckets seated properly. The gearboxes are hitting the radiator support and I'm reluctant to cut up the support to try and make it work. See pix for details.

Was wondering if a couple of people could measure the distance from the firewall to the radiator support on each side of the engine bay right next to the fender. Thinking maybe I could slot the support holes and push it back 1/2"-3/4" as I have room in front of the fan so the radiator could go back a little.

All I want to do is clear the grill somthe doors can swing without hitting anything.ive already put 1/4" spacers in the RS brackets to move the side mounts back, but the doors are still jamming up1/4 of the way closing and don't really fill the hole bc they're cocked.
