Transmission Yolk ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

How much the yolk should be sticking out at the transmission? Would the amount sticking out be the same as my 85 K5 4x4? Do these take a longer yolk then a car would, have yolk out of a turbo 350 that was in a car. Truck is a 81 C20 that I swapped in a 700R4. Switching to a one piece drive shaft. Rear is a corporate 14 bolt full floater. My truck had a turbo 400 with a two piece shaft. I don't want to cut the shaft just in case the 700R4 doesn't work out.

Thanks,
Eric
