Coupler shaft and gear search

I have two 31 AA's, one is the 131" WB and the other is the 157" WB. Both are in the "project" phase. I'm learning the gear on output spline of the transmission, (I believe part #AA4811) is hard to find. I also need the coupler shaft for each of these, because the female splines are worn. I think the shorter shaft is part # AA4815B. I've learned these are also hard to find.

Is anyone aware of a rebuilder who will re-machine the external splines on the AA4811 and the internal splines on the coupler shaft? Or, is there a better work-around?

Or, easier, is there a place to buy the rebuilt parts?

There is a short wheel base one on Ebay right now.
