Looks like its time to upgrade the suspension. Let Geoff and I know if you need any help. Our shop (my garage) is always open and "my dad has an awesome set of tools, dude" (little Fast Times at Ridgemeont High humor). We can fix it.
Dude, screw doing it yourself! Too much work, and you don't want to burn a favor with Jeff on that when you can get the purty stuff from Camburg. Take Jerry's advice (the guy who posted above from Camburg). He is the man and his stuff is beautiful and it works really really good - but you knew that. LOL
Oh, and Jeff, you still interested in that 4.0L?!? PM me.
