3.5" Drive Shaft for Automatics

[tmcolegr]

Does any vendor offer a 3.5" one piece drive shaft (aluminum or steel) for use with an automatic transmission that does not require the pinion flange to be replaced?

I had to make an emergency trip to a local shop to provide my stock DS to replace a badly vibrating 3.5" shaft that didn't require a pinion flange change. Why not go with what works and give Ron a call. The pinion flange is really no big deal. Spydershaft automatic vibration free to 140+ mph in my car.
