the only 3 places I would trust to build my trans are RPM, Rick at rkt56, or Jason at texas drivetrain performance... Jason at TDP built my tr6060 a couple of years ago and it has been doing great, if you happen to be in the DFW area that is a good option

Give him a call and I'm sure you will have a very good feeling for his work.
What have you done to make your differential more bullet proof?? If the differential case splits, many times it takes out the transmission output shaft. Wheel Hop/ drive train shake are the top causes for the differential to grenade.
