Asphalt Truck with LeeBoy Distributor Model 250

Description

1987 GMC C7000.
Starts right up and runs great!  Powered by a V8 gas engine but transmission is bad; it will move around and go up on a trailer.  The rest of the truck seems to be in good working order.
The body is in really good condition, especially for it's environment.  Windows and doors all open and close like they should, glass all good, tires are about 75% tread remaining.  The flatbed is in great shape as well with very little rust.
The interior is a little rough, but is very functional and everything works just fine.
The LeeBoy Model L250 Tack Distributor asphalt equipment appears to work.  Looks to be in great condition and all equipment and controls look to be present.
