Anyone have the number for the correct mopar type master cylinder for a disc drum system? wilwood states i need a 1 1/8 bore, manual brakes

We have run the Cordoba 1 1/32 on our 64 Polara for years. Front discs and rear drums.

Car runs 11.0's 1/4 mile. Plenty of brakes with the smaller size master cylinder with our setup.

The 1 1/8 bore one would be a touch better.

I used a mc for an 80 Dodge Ramcharger with 360. Had no issues with it at all. Same setup, disc/drum. 3400 lb stocker.
