Another Drive Shaft Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I put the BB in, the tranny sits about 1 1/8" forward than when I had the SB in it. Is that too much of a difference to use the same drive shaft or should I put in a longer one?

It depends on how far in the yoke was to begin with. My guess is you're gonna just barely need to get it lengthened, unless it was on the long side before...
