Hi all,

a friend of mine bought a 1957 4100 (1.5 ton)chevy. I went out to take a gander at it and noticed it had 22.5 tubeless tires and wheels on it all around. The odd thing was that the front wheels had 6 lugs and the back duels had 10 lugs. Is this normal or would you think someone has done some switching of axels over the years?

Your thoughts are appreciated.
