Just figured I'd mention these guys for Aluminum driveshafts if anyone is interested. I bought one and it was really nice to see that when it arrived it came with a socket for the 6 new bolts they supplied. It also came with blue thread locker and a reamer to run through the threads to remove old thread lock. Directions were very good and the quality of the driveshaft looks nice too. They seem to be very reasonably priced at $599 shipped with a 30 day money back guarantee. Road tested the car no vibrations took it to 135mph quite no vibration. Allso seemed to help reduce some of that clutch chatter.
