Was originally purchased for my 12" brake upgrade to my Monte but never used. Used an older B-Body M.C. instead which fit better.

Box is beat up but the M.C. is just fine. Part # is: 18030402 check it out on gmpartsdirect.com for yourself. Buy it from me and save a ton. Their price is $71 plus the high shipping cost....

I would like $30 for it. Cleaning house of parts I won't use....if it does not sell within a few days or so it will go on E-Bay.
