Works great but still have the old spring pin to hold the adapter
to the trans shaft. That would be my weak point.

Joe, It looks like your alternator belt is going to be needing to be replaced in the near future. Looks like cracks developing at the notches....

Thinking about the pump adapter, if I do any more of them I'm going to drill + tap them 90degrees from the spirol pin for 2 set screws just for some extra grip on the pump shaft.

Sounds like a great idea Sam. Always good to have some extra insurance.

I would really like to do the CV conversion.
The pics and video are helpfull.

Yes I noticed it when it was done. Was going over the photo's and there it was big as day. Guess I overlooked it when trying to get the shaft installed.
but now it only takes four bolts and the belt can be replaced.

No did not take any photo's of the shaft before installing it. Best I could do is this one. You can see the back half and the weld. Cut a piece out of the original shaft so the two remaining pieces would equal the length I thought would work. Then the two pieces were pressed into a 2" sleeve and welded in a lath.
With room for the joints to move on the splines. Allowing for the flex of the engine mounts. The 15 5/16" was the measurement between the surface of the front adapter and the surface of the rear adapter: On my 782D.

Well I am going with a factory drive shaft, picking it up today. My question is, is there any reason to use pins in the drive shaft instead of bolts n nuts? IF bolts will work just as well, should I use a soft bolt or a hard bolt?

As for the steering gear, I am waitin on the upgrade, and cam follower.

Most everything else is done, small coolent hoses, alt belt, stat, starter conversion, and glow plug conversion are finished.

.

Spirol pins only or you will egg shape the holes and then you will get to replace everything all over.

Thanks for the response Sam, I am having problems finding spirol pins, or even a cub # on them. Anybody have a source? Is two roll pins ( 1 inside of the other ) a bad idea also?

Ace Hardware, Napa, possibly Menards, stores of that type should have what you need. And no, that's not the best idea.
