9" Drums to Slider Disc Brakes

We have a slant-six powered 1965 Plymouth Barracuda that was originally equipped with 9" drum brakes all around. This project documents the upgrade of the brakes on this car to the slider disc brakes used on 1973-1976 A-Bodies. This page is work-in-progress and so far we haven't made very much progress (no time!).

Upgrading these brakes is much easier when a parts car is used since all of the parts necessary for the conversion will be readily available. The parts car used in this project is a 1973 Duster acquired from a Tennessee junk yard through eBay.
