Well the sun shined on my backside today...
Got a call from the guy I bought the truck from and the contents of the glove box 'showed up' at the garage he was at.
So I got back the protect-o-plate and original manuals, Dealer checklist (signed 3/19/72)
Plus an atlas from the dealership to the owner (which I thought was cool) and their maps from when they traveled
I'm one happy camper!!
