I'm looking for a drum drum dual bowl master cylinder swap. I believe it uses a 60's Mustang unit but its been so long since I did the last one. Recommendation or part number please.

Power assist or manual?

Is this the present engine?

Non power. And that picture is when I had the McCullouch on it. I've gone to a 4-71 now.http://forums.y-blocksforever.com/uploads/images/e5907107-fb75-495d-a012-ab48.jpg

If you want to stop, you might need more than just a dual master & drum brakes.

I would play around on a parts store website to find what you're looking for.  Years ago I did a front disc conversion on a 1960 F100 and found that the bore size mattered a lot more than I thought it did...after trying several that were not the recommended size.  The pedal was forever spongy.  Maybe measure what you have now and find a Mustang unit that's Drum/Drum.

Definitely get a master  designed for a drum/drum because they usually have an residual pressure valve built in. Disc/drum masters usually do have have it. Otherwise, , you will have to add two (one for the front, one for the back)

I have a disc drum now due to a planned disc front conversion that never happened. So the front drums don't work so well. The car stops well enough but on the strip I end up at the last turnout. I only go racing about once a year now so I just want to get the drums working correctly. I'm pretty sure its a 64/65 Mustang master. Just curious if anyone had the part numbers. I can get one at the local parts store and then I'll know for sure.

... damn ...

Beautiful assembly detail!

I believe what you want is here - https://www.dennis-carpenter.com/en/cars/brakes/master-cylinder/c9az-2140-d-master-cyl-assy-manual-drumb

It has the RPV's front and rear and is a 1" bore as the 55/56. 

Ask if it is imported or not. The adv does not make that clear.

If imported, this may save you money - https://www.raybestos.com/brake-master-cylinder-mc36222.html

RAYBESTOS has a good quality history and about the only way I know to get USA is finding a take-off and going through it including sleeving the bore.
