You need the transmission/shifter stuff and rear diff to match, of course.
You need to either have a custom 1-piece driveline made or attach the 5SP 2-piece's carrier bearing to your car's tunnel somehow.
You need the transmission crossmember and strut rod/reaction rod plates as they're different between models (according to Jerry - thanks!)
You need the flywheel and clutch stuff, and pedal rack and clutch cable. I'd grab the throttle cable too, just to be safe. And speedometer cable too, probably.
The front axles should fit the same as long as you're getting a trans from a N/A car. Same inner spline count.
Good luck!

An EA82 just needs the Manual drive shaft (IIRC, just the front half)You need to either have a custom 1-piece driveline made or attach the 5SP 2-piece's carrier bearing to your car's tunnel somehow.
You need the transmission crossmember and strut rod/reaction rod plates as they're different between models (according to Jerry - thanks!)
And only need the tranny crossmember. Don't need the radius rod plates.
Axles are fine as is.
You'll need a 3.9 diff... most Autos are 3.7 I think?

Also, I just stuck my head under my coupe and there *is* a 1-piece driveline sticking out of the 3AT

I haven't visually compared the radius rod plates but that's what Jerry told me while I was talking to him about a 5-speed shifter kit.. maybe just grab them while you're at the yard to be safe; they can't cost too much.
Also, I just stuck my head under my coupe and there *is* a 1-piece driveline sticking out of the 3ATsorry Mike! The 3AT is a 3.7 though.
I have another complete doner car, my main thing was front axles, I know the turbo has the bigger spline thanks everyone

Yours is an EA81, his is an EA82. Different. Sorry, but underneath an automatic EA82 IS a two piece driveshaft. And the EA82s do not need to have radius rod plates swapped from my understanding.I haven't visually compared the radius rod plates but that's what Jerry told me while I was talking to him about a 5-speed shifter kit.. maybe just grab them while you're at the yard to be safe; they can't cost too much.

On ALL 4WD EA81s, there is a one piece driveshaft, and its the same manual or 3AT. All EA82s and newer use a two piece.

front axles will work
front half of the driveshaft is longer (manual tranny is shorter).
other than that, you should be set.

the space there the AT's mount is would be a metal plate on the MT.
dont forget the driveshaft! the MT driveshaft is longer on the front half becahse the transmisson is shorter than AT
the axles will fot on the stubs.
you will need the bolts for the flywheel since they are longer than the ones on the flexplate

I typed this then dug round and found something out. The 3at 4wds have a slightly different ratio of transfer Front VS. Rear. Front shaft is driven at 1.023:1 the rate of the main shaft, Rear shaft is driven at .948:1 the rate of the main shaft. What does this mean? Front diff is 3.7, rear diff is 3.9 (or if you go back to the earlier 85,86 and turbo ones 3.454front and 3.7 rear)This means that while the Front diff ratio for 3ats is 3.7, the rear diffs in all of the 88+ will be 3.9s
4EAT equiped GL and Loyale turbo cars are not like this transfer for both shafts is 1:1 same diff ratio front and rear.
