Please Help!
I have a 1986 short bed Silverado, the truck had a sbc 350 and a long tailshaft TH400. I have completely rebuilt the motor and bought a new B&M street strip TH400 short tailshaft. My question, is how much longer of a driveshaft do i need (exact measurement) the yoke on the new transmission is the larger 1 7/8.

Damn not alot of love for this conversation..I just did the measurements for the driveshaft ill be building. Outside of the ujoint style ill need I just know that the caps are different sized on each joint section..Overall length and slip yoke take up are squared away. Been a few years and hopefully you figured out what you are doing.
