Im gonna change my leaf springs from my mono leafs to a 5 multi-leaf setup.. My question is should I bother putting in the rubber pads or is it ok to just not install them?? My car did and is setup for a mono leaf spring, the perches should work right?? Thanks for the help!!

Regarding the pads, I had the same question not too long ago. Short answer is you should use them. See this thread http://www.camaros.net/forums/showthread.php?t=156254 for the long answer.

Regarding the perches. I think you'll have to do something as your multi-leafs will have a much thicker middle and will require deeper perches for proper seating. Either switch out the perches or get some sort of adaptor kit.

Don't forget the shock anchor plates and shocks themselves (not 100% on the shocks)...you'll need to switch those out as well. Do a search here as there is tons of info given you'll be 1000th guy doing this....
