I have good set of front calipers from a 240 I'm parting out. They have more pad surface area than the 164. The 240 calipers almost fit except they are about 1/8" off center. They have some metal built up at the mounting posts (looks like permanent 'washers'), and it looks like it could be a perfect fit if I just grind the washers away.

I remember reading a post on this same subject a while back, but I can't find it. Anyone have a link to that thread or know if this will work?

Thanks,
Adam

Be assured that although the *rear* brakes (calipers and rotors) from a 240 are perfect on the '75 164 -- but *only* the '75 -- the fronts are an altogether different story. I don't know if those "customized" 240 calipers you're planning to make will work well -- and I'd hate to see them fail when you have to "drop anchor" from highway speed. I do know that the rotors are different -- e.g., Brembo p/n for the '75 164 is VO900 front, VO906 rear; whereas for the 240 series it's VO905 front, VO906 rear -- so I would suspect that the calipers are different, too. There might also be differences in the thread size/pitch for the lines -- you wouldn't want to screw up your brake lines trying to hook them up.

Check into all of this before you experiment. Brakes aren't something to triffle with casually.

Good luck.

Yes. That's why I'm hoping to find that thread. I thought maybe someone solved these problems already and could tell me how it turned out.

Some info here: http://www.brickboard.com/RWD/index.htm?id=942012
but you'll have to read all the posts to get a sense of whether this will work for you. It doesn't seem to be 1975 specific.

That's it! Thanks. In that thread, the 140 owners are looking for 160 rotors to pair with the 240 calipers. In that sense, I'm already ahead. Everything else is the same: machining and enlargening the mounting holes and fabricating lines.
