DSE Quadralink or AME triangulated 4-bar

[johnnymac46]

I recently bought a 68 Camaro. It happens to be my first car I have owned several trucks, 70 k5, 70 k10. Ill be the first to admit I dont know a lot about the products on the market and could use a hand. I've decided to start by upgrading the suspension. Its currently stock all the way around, with the exception of traction bars in the rear. I have dont a lot of research, and I have heard mixed emotions. My question is do I need the extra strength of the full rear clip or is the stock frame enough? Also 12 bolt or 9 inch? I am putting in a 454and tko600, and shooting for 500hp. Any help would be greatly appreciated.
