Dana 36 to 44 Question
I finally have the parts together to do my Dana 36 to 44 conversion. I have a 87 convert with a ZF tranny. I hope to do it later this week. Do I need to remove the X brace to swap the C beam and drive shaft? How about the exhaust from the cat convert forward?

Hey Craig, you would need the D44 center section and batwing (rear cover). Then you would need to shorten your driveshaft about 1.5". I am sure somebody can chime in with an exact length. Even if you got a ZF6 driveshaft that the length was correct, the yoke on a ZF is a 32 spline. Your's is a 27 spline. So you need to reuse your yoke. And the last thing is the C beam. You could get a D44/ZF6 C beam, or redrill the holes in your C beam. So the only things that you absolutely need is the rear end. You can convert your driveshaft and C beam, or if the price was right, get the D44 C beam and driveshaft.

You always have a knack for clearing up loose ends
I guess we just need the exact driveshaft length. I wish I had my old ZF/D44 driveshaft. A center of u joint to center of u joint measurement would also clear that up. I will be curious to see how close my 1.5" shorter guess actually is.
Sorry if this is getting off track to the OP. I guess it's still related.

If you read Joby link he states
" The original driveshaft was not too long once in place, but it was impossible to install without unbolting the c-beam and dropping the rear of the tranny a bit "
In theory, you only need a minimum of freeplay on yoke to allow for diff movement on it's bushes.
It's not like a live axle where you have to allow for maybe 1 1/2" of yoke travel @ trans

27" c/c near enough
