Really like what you've done to the ride. Looks great!
Congrats on the new spot and time to work on it, too.
I do have to agree with a previous poster (147?). You have your proportioning valve on the line of the master cylinder (big reservoir) which should be going to the front disc brakes. The small reservoir is for the rear drum brakes and is the system that should have the adjustable prop valve on it. I read where you said it works good, so probably no worries, but you definitely need to make sure that line coming out of the larger reservoir (closest to the firewall/driver) is going to the disc brakes for fluid provision/supply as those pads wear, or you may end up sucking air instead of fluid as time goes on.
Looking forward to seeing the rest of your build!
