OK, how short can my driveshaft be?
Well, after looking a my spreadsheet long and hard on what my CJ-5 project is going to cost and the time it is going to take, I think I am going to have to revise my plan.
THE PLAN was a 5.0 EFI/NP435/D300, axles to come later, probably outboarded D44s, but that is next year or so. Right now I am half down to the fram and I am finding all of the other stuff that needs doen on a '74 that I didn't look at when I came up with THE PLAN. I have the 435 and the 300, don't have the 5.0. Thinking I would like to drive this thing sometime soon.
So...., THE PLAN version 2.8: If I put the 435 and 300 in behind the 258 I save a bunch o' cash and time. But I just got back in from the garage, and my 435 with the adapter is going to come in at 15 inches, and whatever is in there now (T90, T14 I really don't know) is only 9 inches. That is 6 inches out of my rear drive shaft, and I am not too crazy with my driveline angle as it is. I have a CV joint somewhere out in the garage.
My question to anyone who has fought this driveline battle: If I put a CV joint at the 300 and roll my 44 up enought to get a driveline angle ~7 degrees, will that work OK? I have a 2.5 inch lift and run in the desert (rocks).
