haven't had a whole lot of time to do much work but here's a little progress...
new air cleaner
cut a hole in the license plate bracket for the hidden hitch
GM flip down plate holder came in
will sit something like this once it's installed
installed the diamond plate rear cargo door panels that came with the truck. Will get speakers installed soon and have them upholstered to match the truck.
got more of the dash put back in, heater controls, key bezel, glovebox door, radio, and trailer brake controller. The gauge bezel won't fit over the monte carlo steering column that was installed by the PO so that will go next.
restored the original gauge cluster with a new bezel, new glass, and painted the needles white
got the lights wired up and working again
found a local truck parts hoarder in town and picked up the correct 67-72 steering column
same guy also had the hard to find rear door panels that I was missing so I scored those and the cargo area side panels as well.
