BMW: FS: set (4) e32 740/50i rebuilt calipers (e28 brake upgrade)

I have just rebuilt (new dust cover and O-rings) a set of 740/50i
brake calipers. I was going to use them on my e28 535i but have
changed my project car to an e30 and will be partially parting out my
535i for the project so I have no need to install the calipers. They
are from a 1994 740i (e32) and take 302mm rotors in front and 300mm
rotors in back (stock 740i sizes). I am asking $325 shipped (obo).
Email me for pics. There is some good infomation in the roadfly.com
archives (e28 section) about the e28 big brake upgrade.
