69 Notch Barracuda - Rebirth

Also measured for a new/used driveshaft. Yoke bottomed out in trans, U-joint center to U-joint Center minus 1”...

But now I’m wondering.. is it the center of where the U-joint caps WILL be, or the centers of the cups at the front (C) and the rear yoke cup (reverse C). Dr. Diff’s website information is unclear on this.

Hmmm...

My FSM says 48.60”, but my measurement from theoretical U-joint cap center to center - 1 in. Came out to exactly 1” longer at 49.62”. I have an aftermarket trans yoke from Brewers.

Great info on this FABO link.

This all prompted me to remeasure from center to center of caps. This time I got the factory specified length of 48.60” (after subtracting 1”)
