If I remember, the bolt pattern is 5 X 5...or something obscene like that. It had a jury-rigged juice jar type of master cylinder in it that has been long discarded, and brake lines that were just scary at best (made up of a lot of T fittings and daisey chained to the front). I've got a reman 68 corvette dual chamber master cylinder with a proportioning valve ready to go on the car, so there should be plenty of fluid in the system. Rims are also a concern, because the dated mags I've got on the car now will clear drum brakes...and probably not discs. Hence, that's an expense that I don't want to deal with at the moment.
