Did you check out this member's car?
https://lateral-g.net/members/ahola/ There is also a link to another website at the bottom of that page. You can also do a search on "Project Stinkray" that Horse Power TV built. They ran a series of shows on a total make over of one of the crew memeber's Corvette that was just about junk when they started. You can also go to Vette Brakes and Products site they have lots of suspension kits for your car and those offset rear control arms I believe.
