Projects Corvette Universal MC

Question:
I am plumbing my brakes on my 33 hot rod,
(Drum/Drum Manual)
and I was wondering which chamber on a Corvette universal master cylinder is the front brakes? All the forums say the furthest away from the mount is the front and the closest to the mount is the back. Is that correct?
Thanks
Rick

 

Equal sized chambers for drums on all 4 it does not matter. I would plumb it for the cleanest routing

 

I was unsure when I recently did a four wheel disc system using one of those master cylinders. Wanted it to be like the factory intended. According to the Chevy service manual, the front reservoir and outlet is for the front brakes and rear outlet and reservoir for the rear. This is with the master mounted on the firewall. Don't know if it really matters which is which, but I plumbed it this way and have nice brakes.

 

I was thinking that they were the same for Drum/Drum each chamber is the same size.
Thanks the line is getting closer to the MC!
