If anybody in the Nashville area is looking for a cheaper alternative to Crawford theres a shop in Murfreesboro called Performance Concepts. I had my 4.08 gears and LSD installed there. Shop owner, forgot his name, is a real nice guy. Really professional, did a great job and knew his stuff surprisingly. some of his employees are a little shady but overall I like the place alot. Definately going there with any future installs.
