What size socket do I need for the drive shaft nut holding the flange on the transmission side? 1 1/8"? 1 1/4"?

I think the smaller size is for the 1 inch shaft, the larger, for the 1 - 1/8 inch shaft. But a short call to SKIDIM will fix you up for sure.

Don't those Hurth trannys have a unique nut holding the output flange? My 98 looked like it would need a special socket with four lugs to remove it, sort of like a spanner nut...

I have one of those "special sockets" for a Hurth transmission that I'm willing to part with... PM me for details.

I made all of mine, using various sizes of short sockets, I cut them short and ground the edge so it was smooth and square to the end. I always needed one before I could get the owners to buy one, so it ended up costing them, anyway. I also ground a flat on two places with their faces parallel, so I could use a 1-1/4" open-end wrench.

Not the greatest pic, but if you look close you can just make out the square shaped pockets at 12o'clock and 3o'clock on the flange nut. JimN is absolutely correct, a resourceful fella could easily fab up his own socket using some square stock pieces welded to the outside of a socket...

1/4"-3/8" x 1"flat would be a better choice. The minimal thickness would keep it from taking up a lot of space and the width helps it resist bending because the thickness to width ratio is low.
