Thanks for the tips guys, but I had it worked out already. I just started it in gear with the clutch pushed in. All other times I'd started it had been in neutral. It bound up and stalled for a brief moment, then busted loose and fired right up.
I also got my gas pedal linkage unjammed, and made an adjustment to the parking brake so I could maneuver the truck into the garage. I had to cut down the headache rack, but then she fit (just barely). I don't know if I can use it on the lift though, the frame is quite narrow! My lift arms might be too short. I'd like to figure out where the center of mass is too. Kind of a tricky rig to lift.
I know need to figure out why the brake pedal is rubbing on the floorboard. Is the position of the master cylinder adjustable on the frame? Like, with slotted mounting holes or something? Either my MC is too far forward, or the cab is too far backward. The rod going through the floor is rubbing the sheet metal pretty bad. That arm doesn't seem to be adjustable in any way; perhaps I need to bend the rod that attaches the pedal to the arm.
