FOUND 73 Roadrunner: Brake Parts

[Madmopars]

Looking for a master cylinder mounting plate and proportioning valve for a 73 Roadrunner with manual disc brakes. PM with details. Thanks!

I don't think that was an available option from the factory on B body cars.

IIRC was an A body thing.

Is the plate you are looking for different than a PDB plate?

The firewall mounting plate as well as the attaching hardware to the pedal is different between the two and although I'm not an expert, I believe manual brakes were available on the 73 B bodies though I could be wrong. My 73 Roadrunner looks to have been originally manual brakes and I converted my 73 GTX to manual brakes years ago using parts from a 74 Coronet as I recall. I can't speak to the interchange on the proportioning valves yet though.

Edit: FWIW, it looks to interchange from 70-74 B and E body. Doctor Diff shows an aluminum version for $40 but I would still need the pedal hardware and proportioning valve. The search continues...

So you need the mounting plate (yellow arrow in pic) and not the other one (blue arrow in pic) correct?

I have the blue arrow plate, thanks.

I'm looking for one like the yellow arrow is pointing at.

Okay thanks, sorry I can't help you there on that one.

I can’t help with parts but 100% that manual brakes were available on 1973 Road Runners. That’s how mine is and it’s stock.
