dschribs Nov 10th, 06, 06:42 AM I have two shock plates from a 68 (or 69 - not sure) Camaro. The part number stamped in them is 392357C. They are off a mono leaf car. Can I use these on a 8.5 rear ('72 Nova) with multi (J. C. Whitney - 3 leaf) springs? tgifford5 Nov 10th, 06, 08:45 AM If they are from a 69 the mono plates will work with the 3 leafs from JC Whitney. I had monos on my 69 and just finished switching to the 3 leafs from JCW part #ZX942669X, $68 ea. They are listed for Nova's. HwyStarJoe Nov 11th, 06, 07:02 AM The shock mounting flanges are different between multi and mono plates. Mono plates mount the shock a little higher, and use a through-bolt to attach them.... http://img.photobucket.com/albums/v59/HwyStar/MonoPlate.jpg Multi plates mount the shocks a little lower, and use a bolt with a single attachment point.... http://img.photobucket.com/albums/v59/HwyStar/MultiPlate.jpg Using mono plates with multi springs will work fine if you use shocks designed for a monoleaf rear Camaro. Also, fab some spacers that'll fit between the plates and the spring perches on the rear end... to take up the gap you'll have. Otherwise you run the risk of bending the plates as you torque them down. I have a pair that came off my rust bucket that are U shaped because of this. :) dschribs Nov 12th, 06, 07:49 AM great info Thanks guys tgifford5 Nov 13th, 06, 06:28 AM The shock mounting flanges are different between multi and mono plates.

My spring/shock plate I am assuming are mono since I just replaced my mono leaf springs. But my question is regarding the brakeline bracket that looks to be attached on the monos in your picture. Mine were not but were attached by a little ear and one bolt on the bracket(driversside mounting plate). It looks like original stuff not some after thought fabrication. HwyStarJoe Nov 13th, 06, 09:11 AM It's not my picture..... it's from Ricks parts catalog web site. What you have is most likely original and correct. dschribs Nov 13th, 06, 09:22 AM tgifford5 In 68 and 69 only one plate (passenger side) has the emergency brake cable bracket riveted to the plate. The driver side plate uses a longer emergency cable bracket that is bolted on from the bottom (using one of the leaf spring T-bolt or U-bolt nuts). This is because of the staggered shock absorber mounting positions. Only in 1967 did both of the Plates come with the emergency cable brackets riveted on - shocks weren't staggered in 67. apbtrock Nov 13th, 06, 12:42 PM Hmm looking at those pics makes me realize....my '67 with monoleafs, had multi-leaf shock plates I pulled off. Sure looked like the original set-up. I dont remember any spacers or what-not. What was going on with mine, did they just install the wrong thing early in its life, and run a diffrent shock to make it work? | ||
