Yes it will fit. The 1M has an N54 and uses the same gearbox as the N55 135i (GS6-45) So the bolt holes will line up.
The N54's GS6-53 transmission out of a 135i or 335i will fit fine and is pretty much bulletproof. Transmission length is 14mm difference (S6-45 being shorter). This is not a problem since the prop shaft has a slipyoke that expands and contracts quite a lot so you could fit it up no worries.
