I spent some more time piddlin with the truck today. The entire bottom of the cab is painted black. It also looks like the frame has been sandblasted and painted as well. Someone put a lot of time in to building this truck at some point.
On a side note just for fits and giggles......The name that was on the Texas title is.....Jesus! No seriously, It was titled to someone named Jesus and then they sold it to someone named Juan. My brother said he might try to find a Buddy Christ statue for the dash.
