Master Cylinder Help

[troonman60]

I have 70 chevy with disk/drum set up and was wondering if any one knows if a checker reman Parts # 101511 replacement master is a disk\drum setup. I am confused because I have been reading that the resivoirs should be different sizes but this one they are both the same size. Do I need to get another master cylinder?

This is what it should look like. The number is an A1 CARDONE part number
Does it look like this?

It looks like that but the resevoirs are excactly the same size, I thought with disks the front resevoir should be bigger.
