Been workin(no I haven't quit ...............YET)
on more of the little stuff, got the heater box apart , I think I'm missing the fresh air vent, is there a second flap on the pass side(like the round one on the drivers side, there's a rod up there but either the vent damper is gone or I misplaced it(the plastic mount where the rod bolts down was broken?)
Most of the metal parts are painted, just need to order the foam kit to rebuild, got the squirrel cage(Thanks again Jeff) here's the mess after i discarded the mouse carcus!
Red circle around the rod in question!
