Thank you very much for the info Barry, it didn't have the 305 and someone had replaced it with an 80's V8 305 or 350. The guy is selling this truck on the internet, and I was trying to go by just the pictures available. He has it listed as a 63, yet it is clearly a 60-61 3/4 ton. Chevrolet guys usually have it a little better than GMC guys. Just curious, is the Grey for 60 and Black for 61 the same on Chevrolet?

Thank you!
Joe
