All of the Continental parts and equipment were bought by Steve Casner and if thats your flavor of choice he owns CRE(Casner Racing Enterprises). He is a busy guy but very good at what he does. He has changed a couple for me and recerted some cases asd even powder coasted and freshened the dragsters trans.

As for the question at hand, lots of good shops out there. My three preferred ones wourd be FTI, ATI and A1. For me it depends on the application who I would use in that group.
