Hi guys, picked up a set of 320i calipers the other day and have a few questions.

I am using later model struts on my '72--are the discs interchangeable on them? i.e.--are they exactly the same?

I've read a few threads on the bmw swap and it said sometimes they will fit w/o mods--is this for a particular year model strut?? The threads did not spell that out as near as I could tell.

Thanks in advance!

The calipers will need machinging on late 72 and up front ends....

Some 72s used the later-style brake disks/hubs. Some used the earlier style. If you have later struts on your car, and they are different than what you pulled off the car, then get late-style rotors/
