Thanks for all the help guys, Boots that looks great, did you do that?
RMP&0 that looks like a good resource to have, too bad I'm not in that part of the country.
Tom, If I can't find a good place in trenton by the time I get around to the diesel swap I might take you up on that.
I took the measurements I needed from the front, and as it turns out I should be ok with the stock amount of slip.
I received my rear driveline from marlin today, but they forgot to send the 10mm driveshaft bolts I ordered.

I got some free spares from them and they should be here tuesday.
Thats the way things go.
In the process of pulling out all the driveshafts I had around, I found out that if I put a front shaft slip on my stock fj60 shaft I had a shaft I could use temporarily. Its got around an inch of spline engagement enough at least to drive it into and out of the shop.
Man does it feel good to be able to drive the truck again. And I even managed to redo the clutch line so I can shift through my gears.
I am so happy with the way it rides, so smooth, takes turns nice without any real body roll. And the saginaw pump helps me turn the 35's easier than I used to turn the stock 29" tires I had on there.
I still need to put the rockers on, but I have them ready to go. Then once the interior is in and I get the engine 100%, plus slap an exhaust on, I should be ready to get it inspected and road legal.
