Like many of you out there in Lateral G land, once the car was stripped t obare metal, all the sins of the past came to the surface. I wound up replacing both rear quarter panels and a host of other stuff to get it right.
My project, formerly known as Project Panther (it was going to be black) is still a long ways from being completed but is coming together a little at a time. Underneath the sheetmetal is a Wayne Due front clip with C5 suspension and out back is a Hot Rods To Hell Center Drive complete with Track 9 narrowed housing and Strange Engineering third member. Brakes are C6 Corvette out front and Wilwood out back. The rear end has been narrowed and DSE mini tubs installed to hopefully fit the 345s (335s at the very least).
Thanks to all who have shared experiences and helped me along the way so far.
