1957 gmc half ton big back window rare 347 pontiac v8 1955 1956 project chevy

up for auction hard to find 1957 chevy half ton pickup with big back window and Pontiac 347 v8.I was told its all original but not sure truck is complete would make a good restoration project. The tranny is a 3 on the tree I was told the pickup ran about 5 years ago runningwhen parked I tried by hand to turn it over but wouldn't but I didn't try very hard and the spark plugs were pulled and put oil in the cylinders.Thanks!!
