double cardan DS donor

I need a double cardan drive shaft for my sled and there is no chance that I will buy a new one. I would like to find one in the junk yard and shorten it in my shop. I need help identifying the appropriate donor and year. I have a dana 300 t-case and a 78 cherokee dana 44 rear. I have also done a spring over if that is relevant. I seem to recall reading an XJ front DS is a good one to look for, can't remember which year though. Also, the yolk from the XJ will or will not fit the dana 300??? Thanks for clarifying this for me.

Or find a front driveshaft and output yoke from a full size jeep. If you can find a 70's with a quadratrac, I think the fine spline front output yoke will fit the rear of the dana 300.

AMC Eagle (all wheel drive) used Cardan joints and some will bolt right in CJ's with no modification.

And it's a CARDAN JOINT,
NOT a 'Double' Cardin Joint...

Double Cardan joint would be 4 U-Joints back to back!:Shocked:

Virtually all the NP case vehicles and the Q-trac vehicles use Cardan joints to cut down on vibration on the T-case output bearings.

I pulled a front drive shaft out of a 70's Waggy with an auto and V-8, awhile back. The shaft was good but the yoke on the quadratrak was 10 spline so it will not work with a Dana 300. I am looking for a new yoke now. The shaft was 25 3/4"" long collapsed and I could not get it to extend past 27".

I hope this helps with your search.

Wrong. A single u-joint is a cardan joint.

The early 70's quadratrac used the 10 spline yoke. The later 70's used the 26 spline yoke.

The rear output was always 10 spline.

If you can't find one in a junk yard, you can order a 26 spline CV output yoke from 4 wheel drive hardware for $43.

Another vote for the full size Jeep front shaft. I don't know about where you are, but around here there are a lot of them in the yards, so when I went driveshaft shopping I got two.

Once apon a time I played with legos... Now I have a Jeep
