I bought this off ebay last week, looks like a good piece for the $$$$$. Item #170570091472 the webstore is buy911. 169$ included shipping, the unit mocked up nicely. The booster is 7" some say bigger is better, but the 7" booster has to be an improvement over stock. I did not bolt up the linkage, so I can't say how the fit is on the pedal arms. The website has some unbelievable prices on disc brake conversion kits, but its almost all Chevy stuff. Check it out. Mark
I purchased one the other day from Macs for about the same prices. Have not installed yet but will soon. Will keep you posted.
