Thanks to some other guys on this site, I was connected to Mark at
http://www.scandc.com/
As I was led to believe, Mark really really knows his stuff concerning A-Body suspension. He's a Chevelle guy at heart, but don't hold that against him. If you're looking for bargain basement cheap components, Mark is probably not where you want to go. If you're looking to build a really nice suspension under your car no matter if it's a F, A or G Body, give him a call. The quality of the items and the thought put into the total package is great, and the support and knowledge is awesome. If you want to see some of the components I've got some pics at
