You have to use a Disc/drum master cylinder, because you need more fluid pressure to operate the front discs.

Or a wilwood proportion valve NO
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

the only thing not saved from the duster was the combination valve. Whats the best source for one? Save yourself a LOT of grief... Find an OEM prop valve...

I like to use the prop valves out of Diplomats, there are two to choose from, 10" or 11" rear drums, just get the one that matches your rear drums.

Now that you mention that, it rings a bell from way back that that is indeed the best choice & another adv of an OE unit is you can retain the OE warning light

In conjunction with a stock combination valve, yes. By itself (he has no stock valve) no.

Because any aftermarket adjustable proportion valve only provides one of several functions that a disc drum combo needs to work properly. It is a tuning aid, not a replacement. http://stoptech.com/technical-support/technical-white-papers/proportioning-valves

I put changed to front disc's on my 70 Sport Satellite - it had manual drum brakes, left it manual disc brake - used the aluminum master cylinder with adapter, from Dr. Diff. It is not hard to brake and works great !
FYI . . . on my 70 300HURST I changed to disc also, but never touched the master cylinder - other than to make sure the check valve was not in the master cylinder. Knowing the master was drum brake, I just made sure to check the reservoir monthly, and never was an issue - pain in the butt, but not an issue . . .

I used a Diplomat MC on my car with zero prop valve. I have 73 Charger discs on front and Wilwood Dynalite on the rear. Car stops on a dime with no issues. I used to have 4 wheel drums with a Volare cast iron master with zero prop valve and didn't have any issues with that either. The only reason I switched to discs was I am in the tens now and after I go a few round the drums were starting to fade. If I were going with some sort of valve it would be the Wilwood. Gus
