About to pick up a T-98 for a transplant

I have an M-38 with a '71 CJ5 drive train swapped in. It therefore has an F head, T-90, and the large hole Dana 18. I called AA and they have an adapter for the t-case so that end will, at some point, be able to be addressed. My question is, has anyone got any good tips on getting this T-98 bolted up to the back of my F head? I have looked at several of the T-18 tranny swaps and SM420 swaps here on the board so I have a good idea of what is ahead. Just wondering if there was any new info as of late or anyone who has done this exact swap. The T-98 will be coming out of a '67 M-715.
