'82 I thought you had converted your D300 to a flange type output. I remember that from another thread.
I used the Explorer driveshaft and it worked out great for me. I had it shortened and balanced at a local driveshaft shop.

That depends on how many splines your Dana 20 has. Most likely it's not the 10 spliine and you can use the front yoke off of a pre-1980 fullsize Jeep with the Quadratrac transfer case or one from an XJ or TJ with the NP231 transfer case. Any driveline shop can also get the correct Spicer yoke.

You don't need to change the yoke on the rear axle. Use the one it has. The one at the transfer case end has to change because the bolt pattern is different with a CV shaft.

I would modify or replace the one on the rear axle to use U-bolts instead of the weak straps.

will the yolk off of a dana 300 transfer case with 26 splines work on my dana 20 with 26 splines for the double cardan drive shaft? i picked up a front drive shaft off of a 96 cherokee and now i am looking for the correct yolk for the rear of my transfer case.

Yes, they are the same spline count and diameter.

I'm having troubles. I got the front driveshaft and yoke off of the 231 to put on my 300 shortened driveshaft and went to install yoke and it's too big. The diameter of my 300 output is much smaller than the 231. Anyone else had this problem? Where can I get the right yoke? Is there a doner vehicle I could use?

Was it off a 231J? There are various models of 231. I got my yoke off a wagoneer with BW1339 tcase, they work on the D300 as well

It was from an xj. I guess I can go look at several different ones at the junk yard and try to find one that's the right size. What can I use for the front driveshaft?

The front shaft is long enough that you shouldn't need a CV type shaft.

I'm SOA on 2.5" lift springs and single cardan is fine in front. Unless you have a Dana 300 that's clocked, even with SOA an single cardan usually does the trick.

Remember, you're not usually driving down the road at speeds where driveline vibrations take place with the front driveshaft spinning.
