I got this part number from Walcks site.  909476

Put that into the napa site and got this part number. NPJ P365

I don't guarantee they are correct, but it's a start.

365 is too big, cant get the snap rings onto it if it was installed. 

that was the first one i tried.

The original Spicer part number was 5-74X. This is from the original Spicer Bill of Materials for Model 25 Dana-Spicer axles.

5-74X has been superceded by 5-260X. 5-260X is identical in all respects to the 5-74X except that it is used in later model open knuckle design axles. To use the 5-260X in a closed knuckle design axle just remove the seals from the u-joint cross. This allows the oil in the knuckle to circulate in the needle bearings inside the u-joint.

Sometimes while removing a u-joint from an axle shaft the yoke will get sprung slightly. When installing the new u-joint, the sprung axle will make it appear that the new u-joint won't quite fit. If this happens a gentle rap with a hammer on the side of the yoke that already has the snap ring installed will bring the other side into the correct alignment so that the other snap ring can then be installed. You need to make sure when installing any u-joint that a needle bearing does't lay down in the bottom of the cap. It is best to pack a little light grease (#1 or #2 EP grease)in each cap before each is installed in the yoke so that the needle bearings will remain in place during installation.

Personally, I recommend only genuine Dana-Spicer u-joints because they have smaller needle bearings in the joint cap. this allows more needle bearings inside the cap. That gives a better load performance because there is more bearing surface applied the the joint cross trunions and allows the trunion diameter to be larger.

If you don't plan to use Dana-Spicer u-joints as a replacement, any competent parts store counter-person should be able to interchange the Spicer part number to their brand of u-joint.

thank you for this knowledge! with this taken into consideration I've found a joint that works it was a moog brand. 
my local parts store (bumper to bumper) ordered me 6 different joints to find one that fit.

The problem with most auto parts stores is that when they converted to computer catalogs they didn't save the old paper catalogs. The computer catalogs only covered later model cars and trucks, say from 1970 or so on up to the very latest models. This is because most models earlier than the 70's have long since been hauled to the salvage yards and have been recycled into other uses of steel, etc.

Old paper catalogs had parts number interchanges, size listings, and sometimes even illustrations or pictures to hekp sort out the complexities of parts identification. Computer cataloging doesn't always include these niceties. This is why Bumper to Bumper and other brands of stores have to order several part numbers at time in order to find a part that fits.

Specialty parts houses will always know what part fits what. Places like Walck's, Kaiser-Willys, Ron Fitzpatrick, and others are probably the best places to shop for obscure jeep parts.

I have been told that the Moog 365 ujoint is a direct replacement for it. 

Here is the post look at the last few posts;
