Hi all,

I just bought some calipers from an early 80's BMW 320i for the teener. I've heard that they have to be machined slightly to fit. Does anybody know how much material has to be taken off, or the best way to measure how much to remove? They will be going on to a 74 2.0L. I haven't tried to install them yet, but I'm assuming that the mounting ears need to be machined down a little so that the rotor is perfectly centered in the caliper, correct?

The "other 914 site" has the article that covers how to machine the mounting bosses. The biggest problem is they have to be parallel to each other and to the rotation of the rotor. Most machine shops can easily jig them up.
