I went with Stainless works. I like them. That being said after the install they did hit the floor on hard acceleration. So I put in prothane mounts on Tranny and engine. No more problems there. It did raise the engine a little so then it was rubbing on my SS hood. To solve that issue I put a small spacer on the tranny mount to lower the front of the engine. All good now. Vibrations are very noticeable now but I am getting used to it. Good luck.
