Hi there, there are only a few 4th Gen folks between here and pro-touring.com
Basically your right. Any trick for a 2nd Gen will work on the back. For the front it's really more of the same. Keep in mind 1st gen Camaro/2nd gen Nova spindles are called "short" ('67-'74) while '75 on are called tall, cause thier taller than the short.

Only look into tall spindle parts. Basically control arms, spindles, brake, and steering links are all swapable according to Hollinger (sp?). Search and read up on what the 2nd gen guys are doing. They're just getting some love from the aftermarket which helps us out.
My car will have a custom subframe and a HTH truck arm set up in back when it's done.
