Holidays and recuperation aside, I haven't been able to wrench the GMC for awhile but finally got out for a quick looksee and checkout some parts received.
Among a few drops of red and green colored fluid collecting under the truck was a large puddle of clear fluid that passed the brake fluid smell test. Further observation concluded the master cylinder is leaking, probably from the rear seal(s). The power brake setup looks alot like pics of kits I see of classic part conversions. So now I need to ID this OEM looking master cyl and determine if a rebuild kit or complete MS is needed. Anyone with a similar setup may know what yr/model this MS came on...
I picked up a DualJet for next to nothing and it ends up being worth about next to nothing. It has the mixture control solenoid which means it needs an ECM and other sensors in order to work properly. As is it would run way too rich (in it's default state) and not worth adapting. Shame, it's very clean and looks NOS. I cleaned up the MonoJet and depending upon what I find under all those manifold adapters it may get bolted on. The dual pulley for the alternator arrived and looks like it'll work. The plan is to get back on it after the holidays.
