A local scrapper had a 66 GMC on the rollback today. I bought it for $400. Same as scrap price it will weigh 4000 lbs. It is pretty rusty has a six and a factory granny four speed &leaf springs on the rear. Kinda rare for a 1/2 ton. I filed the points and hooked a gas line to the carb. it fired up and ran really well no smoke or blow by. I drove it around a little bit. Any road it has a lot of good parts. the glass is all good also.
