I am trying to figure out if I can use the drive shaft I have in my '68 Coronet 440/727.
I have the rear springs resting on jack stands
and the slip joint in the tranny as far forward as it can go. Slip joint middle of eye to pinion middle of eye is 53 inches. The drive shaft itself is slip joint eye center to rear center of u joint is 52 inches, is this too short?
Also the tech archives lists my shaft as 55 x 3.0.
Why would I have a 2 inch difference?
Thnx

With the slip joint all the way in how far is the rear joint from being seated in the pinion yoke?

With my spare slip joint in all the way it is 53 inches center to center. I am going out now and measure what you asked.

Stumpy, with the slip joint all the way forward there is a gap of 7/8 of a inch from the rear most of the u joint cap to fully seat in the yoke.

That's good. 3/4 to 1" of the slip yoke out of the trans to seat the joint in the pinion is right.
