Hello,
Does anyone know for sure if the E28 M5 diff will directly swap out with the differential of an 1986 635csi? I have an opportunity for the M5 differential but I will only act upon it if it is a direct swap. I do not want to get involved with changing out the input shaft etc.
Please help
I didn't find the right solution from the internet.
