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.

Welcome to C10 trucks enjoy your stay .....rather than guess I'd put it together then measure anim_25
