'79 Master brake cylinder front/rear lines

Does anyone know for sure which reservoir goes to front or rear for a '79 master brake cylinder for manual brakes?

Right now the reservoir toward the front is smaller and is going to the front brakes.

This is a new installation...the one that came off was from the '74.

 

The larger of the two is always front on a disc/drum MC.

 

I haven't swapped the brakes yet...it's still drum on the front for now. I wonder if it matters then if it's all drum at this point.

 

nope still want more fluid to front hence the larger res.

 

ok. thanks.
