Run, don't walk away from Duntov Corvette! I've heard nothing but bad about them.
And I don't think the money for the Shark Bite suspension would be well spent. Obviously Danny Popp is doing just fine without it.
You said this will be a daily driver. That being the case, I would keep it simple. I would start with rebuilding the trailing arms. If you want to upgrade a bit I would go with
Global Wests TAs
You already have the VB&P strut rods with the spherical rod ends. I would add VB&P's
Smart Strut BracketT if you don't already have it and also their
Rear Dual-Mount Spring Kit. And top it off with
Bilstein Sport shocks.
And with the 502 engine you may want to beef up the differential, halfshafts and spindles. Depends how hard you are planning to drive it.
