I've had a few questions about the T5 swap, so here are all the parts and a high-level overview of what I did to make it all work before I forget completely.
If you're thinking about doing this swap, read this document at least three times:

I'm running a Kaplhenke adapter plate and machined bellhousing. The adapter plate has the pattern for both upright and slanted orientation, allowing for the B20's upright orientation. The m46 bellhousing bolts right to the back of the B20 with no modification other than the machining done to open up the center.
- I'm using a clutch from a 4 speed 4 cylinder Mustang (Sachs SD1220).
- I have a 4 cylinder T5, I'm using the pilot bearing from a 1984 Ranger 2.2L diesel (National 202-SS).
- If you have a V8 T5, you'll want to use the pilot bearing from a 1985 Peugeot 505 (National 103-CC).
- I'm using a stock 140 pressure plate (same as early 240's as well).
- I'm using a stock 140 clutch cable, 240/740 cable clutch fork, and Yoshifab's modified T5 throwout bearing.
In terms of a driveshaft, I had a local driveshaft shop do everything. The back 1/2 of the driveshaft is 100% unmodified aside from balancing. The front half was shortened and a slip yoke was added. When I took measurements, my guy just wanted the length from the output shaft seal to the center/middle of the carrier bearing. I put the M40 with bellhousing and t5 with bellhousing side by side and basically measured how much shorter the M40 is than the T5 and then subtracted that distance from the length of the front half of the driveshaft (from the output shaft flange to the midpoint of the carrier bearing) to get the length he wanted. Your local driveshaft guru may want something completely different, but I'm yet to have an issue with mine.
I took my M40 cross member and basically kept cutting it until I could make it clear and get the T5 high enough. I then added a 5"x1/2" c channel longitudinally for the mounting pad for the transmission. It's ugly, and I'm not posting pictures of it. At the time (July of 2019), nobody was making cross members for this swap. Yoshifab now makes a $200 cross member for these cars and the T5, and that's the way I'd go if I did it again.
