Tranny swap
I'm swapping a m5r2 into my 84 f250 which had a c6. And 2 issues came up. That I kinda knew were coming.
Problem 1
What would be best approach to this cross member situation? With the longer transmission the original doesn't fit in its old location. Or with the cross member supports. Would I be able to drill new holes and mount it farther back? Would the cross member from the donor truck fit? Donor was a 88 f150.
Problem 2
It looks like one of the front driveshafts I have will fit but the rear won't. About an inch too long. Would I be able to use one from an extended cab that had a m5r2 in it? Donor was single cab long box its new home is extended cab long box. Or do I just take mine in to get shortened?
Thanks guys you have been helpful on this it's taking too long to do this tranny swap. Course it doesn't help having a broken thumb right now.

You must move the cross member and properly mount the transmission at the correct angle. You can try the other cross member, it may be easier to use due to the existing mount. With the transmission supported, remove the old cross member. Compare it to the other one. If it's the right width etc, bolt it to the transmission and mark where it needs to mount and drill your holes accordingly.
Drive shaft. Have new shafts made to match your new dimensions. Make sure the rear shaft is the correct length and won't bottom out.

If you move the crossmember, you need to drill holes and remount the upper short pieces also. This keeps the frame from twisting. When I did my zf swap I had the proper donor, the upper crossmembers used the same holes, they just had more of a twist to the crossmember. The zf was about 1 inch farther back like yours.
Not sure you are going to find a stock driveshaft to fit. They never put that Mazda 5 speed in a f250 or f350. So you might find a f150 shaft that would be close, but the u-joints may not match up, since it's a f250 they may be larger and the rearend may be larger so the pumpkin yoke can be farther forward.
