Modification to a 4 drum master cylinder for use on 4 wheel discsv. ?
Current set up, factory KelseyHays front discs, drum rear
Plan , rear discs kit from pirate jack, I already have the kit.
I have been unable to find a new factory OE MC for the factory disc/drum set up.
Picture here is a new MC from NAPA
That was listed for 70 Dart disc or drum
I remember a post that to use the 4 drum MC shown here, saw it could be modified to use when adding an aftermarket rear disc kit. I can't remember clearly , something about removing a " restrictor " or a "valve" just before the bosses to install the lines. And also using an adjustable proportioning valve for the rear ?? .
I am trying to keep all my speed and stock parts "era correct". I know about Dr Diffs MC kit with firewall mounting adapter, which, being aluminum and plastic is definitely
Not era correct.
Does anyone remember the post, or know what to do ??
