I had to shorten the shaft slightly in order for it to mate up with the steering box ('79 half-ton, power box). To shorten it, I drilled through the plastic shear rivets and then using a mini-sledge and a 4x4 block, I compressed the shaft to get it to the length I needed.

Great information. Thanks
