Re: 3/16 or 1/4 in brake line for all drum brakes?

just wanted to confirm - you had 3/16 going to the rear in a 65? My 66 had 1/4 all the way around (all drums), which is what I expected. I thought 3/16 line didn't come into play until disk/drum combos came into chev trucks in 71(?) Interesting.

Concur - gotta have the correct mc. I'd recommend do the whole thing all at once, even if it takes a little longer (i.e. to include front disk conversion now, rather than later - IF you plan to do one). That will guide your mc and line size choice. If disk/drum combo - 3/16 to front and 1/4 to rear is correct. If you're going to stay all drums forever(!) I'd personally do 1/4 lines all the way around (and a new mc for all drum systems - 67 impala mc is a good choice for this), power or manual depending on whether or not you have a booster, there is a difference in the mc's for power vs manual and 4 drum vs disk/drum).
