Yes, the diameter of the piston is the bore diameter.

Here's the new mc I'm going to try and work with, the bolt holes are maybe 3inches and 1/4 instead of the 3inches and1/8, the hole the push rod goes into looks the same, I havent stuck it in there to see if it's a good fit, ran out of time before I had to leave for work.
there is a black rubber boot that came with the mc, the hole in the boot is super small compared to the push rod size that I'll be using, the same one that was used with the single mc already on the rambler. If the rod is just a little too big to go into the mc, I could get the rod lathed down by maybe 1/32 or 2/32, just to make sure it won't bind as it moves. I think I can open up the bolt holes on the mc a little and make it work, and use the two bottom holes in the firewall, but the dual mc is alot heavier then the single and hope the two bolts will be enough to hold it as time goes on. The front port is 1/2 The back port is 9/16 Tomorrow I'll look at some adapters or reducers to connect the 3/8 nuts into those ports, and also a npt three way for the stop light switch.

Cut the rubber boot not the push rod. I have had a similar MC on my 62 Classic, enlarge the mounting holes, I did no problem for the last 12 years using 2 studs with nuts.

Oh! I think you got the wrong idea, I meant lathe down the push rod so it won't bind in the piston of the mc, and that's good news the two bolts will be enough to hold it no problem.
Wait a minute... You said use two studs with nuts.... I can't do that, (of course I can, just read on....) because there is threaded nuts welded on the other side of the firewall to accept the smaller size of stud used with the original, smaller mc, I'm sure the holes on this new mc are meant for studs little bigger (might have to do a fact check on that) and I would need to drill out the square nut to use the larger stud and nut... Did you mean "enlarge the mounting holes" of the mc, or the firewall? Also I was going to use the old rubber boot that's still on the push rod.
Wait a minute... That rod moving back and forth wouldn't bind, because it wouldn't move back and forth in the piston, it's the piston that will be moving in the bore of the mc, being pushed by the driver at the brake pedal, and being pushed back by the spring in the bore of the mc. I geuss the only problem could be is to make sure the alignment of the piston for the push rod is not a problem..

Enlarge the mounting holes on the MC. Use the studs that came with the firewall mounting for the original MC
