CPP Remote Brake Reservior

[bmnk]

Ok.... so a couple years ago I bought the CPP Master Cylinder Adapter Bracket, to upgrade to the dual reservoir master cylinder. I bought the master cylinder at one of the local parts stores.

This spring I bought the Remote Reservoir kit also at CPP. So today when I went to install the master cylinder cap, I noticed it it's different then the master cylinder I had originally installed, as my master cylinders has two different sized reservoirs. (smaller one in the front, larger one in the back).

SO my question is.... what is the correctly master cylinder I would want to use for a manual 4-drum brakes setup, that will work with the adapter bracket and remote reservoir kit?
