well, no one might be interested in my build, but I'll keep the updates going. I tingle with updates, no mater how far apart lol. I worked on getting my cherokee shafts ready for the truck. I bought two at the junkyard, and one on ebay for much more money

, a plan B I didn't need.
Here are some direct pictures of the two shafts I have.
One used 7/16 bolts and the other used 13mm. The pivot joints are slightly different on each, but the splines and "D" shape measure out the same with my calipers.
I heated each one and pulled them apart. Neither shaft had any rubber inside, only rust and the plastic "spacers" or sleeves. They didn't have any plastic or rubber pins visible from the outside.
Here is one pulled apart and ready to be welded. The other behind it.
Here are the plastic spacers or sleeves some people have been finding. Don't throw them out. Even though I'm welding nuts on and using set screws doesn't mean I wouldn't mind the plastic taking up some slack.
I snagged some SS set screws from work. I had some nuts in the garage that work

I drilled a 1/4 hole, filed out the inside, and wire brushed the outside so it's ready for welding. The long bolt is there to get everything straight while welding. It fits tight.
