As you know, there are 3 "propeller shafts". All have slip yokes. The slip end, according to 1960 GMC manual (same T221 and system), is as follows: Front diff shaft: Slip at TCase. Transmission shaft: Slip at transmission. Rear shaft: Slip at TCase.
Be sure to note that there could be factory stamped arrows on male and female slip assy. Should be aligned and pointing to each other. This is what GMC shows. Chevy= not sure. I have them on my 1960 GMC 4X4.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
