I am in the process of removing an engine from a Euro 735i to a Euro 535i, and wanted to know if it was common for a E23 Euro 735i to have a 5spd, Oil cooler, L-block, and a LS Diff?? I can not believe the goodies on this car, my E28 will receive all :) Will I have any problems swiching the parts to the E28?? I know I will have to change the motor mounts, but what about the other parts??
