S5 n/a transmission into S4 n/a, which crossmember to use?

Sorry guys, but this has come up several times on the 'other' forum. I'm going to assume that you are referring to a manual transmission and not an automatic.

If you refer to the RotaryResurrection articles, it will become clear: the body determines what crossmember you need, not the transmission. The center stud on the transmission will line up fine, but the passenger side bolt holes on the crossmember are different between s4 and s5. S5 is flat on both sides while S4 has a steep angle on the passenger side. The center hole where the transmission stud goes through is in the same place either way

S5 looks like this -\___/-
S4 is like this -\___/\

Hope it clears up any confusion
