like he said....cab mounts and bushings are a biggie. On a truck that's 34 years old, the factory rubber mounts are cracked and maybe even gone in some cases.

To do it up right and be happy, plan on spending probably $400 for springs and shocks all the way around, then the cab mount kit and suspension bushings. That'd be your best bet. I'm sure there are board members who sell cab mounts and suspension bushing kits too. Keep the $$ with the board members (bought my stuff before I found this board
