I have a 67 camaro with monoleaf springs. I'm going to put multileaf springs on it. I will be cutting the spring perch off and welding a new on. I have heard that you can use a mopar style spring perch with two u-bolts (the flat perch like 4x4s have). I searched but couldn't find any part numbers or specific applications to ask for at the dodge dealership. If anyone has this info could you post a link or the info itself please? Thanks in advance.

Also am planning on using a spring rate of about 150 or 175. Does this sound about right? I have done multiple searches and this is what I think is the right rate. The car is basically a weekend toy used for cruising, a little track time, and I want it to handle well. The motor is not very high performance right now but when I build it I will be shooting for around 500 horsepower with a lot of low end tourque. I'm not too concerned about ride harshness as I'm used to riding in old 4x4s which are very stiff and the car probably won't be my daily driver. Any opinions on the spring rate would be appreciated.

Here's the answer to your first question....

for your question about spring rate, what rate are the front springs? small or big block, etc, etc....

I was given the option of GM factory style perches or universal when I had my mono perches replaced. I don't see a problem with the mopar (universal) but why not just use a plate with a center hole to replace the pad and run the mono perches.

I opted for the factory multi's (at a higher cost) for the fact that the spring fits inside the perch and with the shock plate in place it looked stronger. I was interested in the factory look also...

Bret-Thanks for the link. Thats exactly what I've been looking for.

As for the front spring rate, I believe the springs are stock. I will be rebuilding the front suspension as soon as I have money since all the bushings are shot and the springs are sagging so I can change the front spring rate to whatever it needs to be. Any suggestions about that would be welcomed.

The car is a 67. It has a SBC 350 (the motor has no significant aluminum parts), no AC (may be an option far in the future), Power steering, TH400 auto. Anything else you need to know? Sorry, I should have included this pertinent info in the first post.

DJD-I have done many searches here on the board and have come up with many different ways to do this swap. I haven't ruled out using a spacer but I thought cutting the spring perch and welding on a new one would look cleaner. When a spacer is used it needs to be welded to the spring perch right? The reason I was going to go with the mopar perches is because they are cheaper than stock replacement multi leaf perches. My car is far from original so that is not a big deal to me.

Novaderrick- I may check around for something like that, thanks.

I got my Chrysler perches from the same rearend shop that welded them on. About $40 total including some extra gussets to make them really strong.

Rockymtnracer- What shop did you use? Were you happy with their work? If you don't want to post it you can email me. ratchet67rsss@hotmail.com

I live in Denver during the week and Fort Collins on the weekend so I may check out the shop you used.

Ratchet

novaderrick i was wondering about the perches too, i'm gonna use the universal ones, i saw the picture on your site, and thats what i'm gonna do, thanks!

Ratchet, I think you'll be fine with the rear spring rate range you're looking at. Take a ook at David Pozzi's first gen susp page to see a chart of compatible frot and rear spring combos. Also, a few guys here have complained of breaking fiberglass leafs with the amount of hp you plan to run so you may not want to go that route.

I don't think the spacer would need to be welded but don't think it would hurt. A nub to sit in the mono alignment hole would keep it in place. With 2 u-bolts I think it would look a bit more factory than mopar perch. From others comments it sounds like the mopar work very well and are half the cost or less of the GM multi's that I sprung for at $80 plus welding...

Ratchet -

The shop is Western Drivetrain in Aurora- call Bill Abel at (303)364-8098. He's done good work for me a couple of times at a fair price. Good guy to deal with.
