I may be getting a hold of an S5 n/a engine and transmission to swap into my S4 n/a. I was looking on Mazdatrix, and noticed that 2 different transmission crossmembers are offered, one for S4 and one for S5. Which one is required to mount an S5 transmission in an S4 car? Does the transmission or the chassis dictate which mount to use?
