1983 GMC extended cab $1500
--------------------------------------------------------------------------------
ya its a squarebody extended cab. this truck is very rare. GM did this conversion on only a few hundred from what i am hearing. the VIN history tells that it is a 1983 GMC 2WD 1/2ton two door 6001-7000 gwv and came with a 6.2L diesel motor and manufactured in ST. Louis, MO. The truck comes without the drivetrain, bed, front bumper, or hood but other than that it is a complete truck. it has power windows and door locks. all the A/C is there except the compressor. Because its a 6001-7000 GWV truck it has hydroboost brakes instead of a vacum booster. it has some rust on it below that driverside rear window and on both of the A pillers. I have an extra steering collum, extra mirrors, from my 81 that comes with it.
