Power Disc Brakes Proportioning Valve

1970Dart198 said
The guy who put in the power brakes used my brake lines from when it originally had drums all around. I believe he used the same proportioning valve as well, it might be a little different. But will this proportioning valve I have posted work with the old drum brake lines?

Thank you for your response!

I converted to front discs also, not mopar, but I kept my drum brake lines. I haven't swapped the P valve yet, but I am sure they are the same thread sizes, they just operate differently. I would just give them a quick call, but I feel very confident that this is what you need.
