Welcome! Do a search on here for "driveshaft" under Drivetrain and Suspension and also under General. I do not know of a place myself, but I know that question has come up a few times before.

So the NNBS crew cabs are one piece too, are the extended cabs? I thought they changed both to 2 pieces.

I just had mine blow out on me last night! It was a 61" steel shaft. It was alittle scary! I just passed 120 on the speedo then I got a bad vibration... let out of the throttle then boom! I made skid marks on the highway. I guess when the drive shaft hit the pavement it locked the rear for a bit before it broke away... Im trying to figure out what drive shaft to go with. The shop said they could do 3.5" tube front to back with .083 wall tubing vs the 3" to 3.5" with .063 wall tubing. That would be using the stock joints. Or they could do a 4" steel driveshaft with 1350 joints...

10,000rpms balancing WILL solve the problem

If you are putting trans in second gear on dyno isn't that going to give you false numbers?
