Shout out from a newbie

[Bone Stock]

Kevin here. I just bought a "yard find" 67 GMC C25, bone stock, 305 V6, column shift, power nothing. Minor rust through on the fenders and a bit more than minor on the cab floors - but localized to the outboard foot areas. Everything else is original and pretty decent. Brakes were down to one rear working.. flex hoses were decayed to the point of failure. I snapped the brake line on the LF, trying to loosen the hose.. so, guess I'm paying for stupidity on that one. The heads are out at the hot-tank, along with the intake and the thermostat arch (?). Years old dried oil nastiness had to be dealt with.
