96 corsica from 3.1 to 2.2

Can anyone tell me what is involved with this

when changing from a 3.1 to a 2.2 you have alot to change. for example the motor mounts. the wire harness and the computer are the main thing. you have to change the tranny to cause one from a 3.1 will not fit on a 2.2 which means you may have to change the axles too.
