I have done this swap M47 to AW-70 on a 92 245. The items the others have stated are correct. The items that are real pains are:

1: Swapping out the pedals is a pain and seems to be easier with the dash out.
2: Rear end swap is a real pain, but a must to maintain stock torque levels.
3: Don't forget to plug the hole in the firewall where the clutch cable used to run.
4: To avoid the nightmare of adding the OD relay circuit, get a solenoid bypass plate from IPD, or grind a bypass groove in the solenoid face.


Finally, DO NOT replace just the front half of the driveshaft, replace the entire unit, otherwise balancing issues will cause problems. At least on a 92, the same trans crossmember is used for both the auto and manual trans, it just migrates to a different set of holes in the bottom of the floor boards. Someone mentioned that the flex plate bolts right up the the flywheel, I'm sure that was just a typo, it bolts right up to the crank. If you do unhook the trans from the engine, replace the four torque converter bolts and crank bolts with new ones, they have a thread locker compound on them that can only be used once.

If you have specific questions about the swap, email me off-line and I'll do my best to help out.
