i pulled the t-case and FM-145 today and got everything ready for the M5OD that i will be picking up later this morning

i know i need to keep the flywheel, bellhousing, pilot bearing, throughout bearing, clutch release mechanism(s), flexplate, torque converter from the FM-145
this is the noob questions, and i know the answer, but i just want some back up on the answer.
i also keep my slave? and my clutch for my 2.9l will work on the 4.0's transmission? crossmember will stay in the stock location? and my transmission will mount to the crossmember the same (so ill still be able to use my "ghettoFab" tranny lift)?
thanks to all in advance, just double checking before i fork over the $$ and realize i am retarded.
