East of the Mississippi the Budd wheels were rare I think on Chevys and other single axle gas jobs. My dad and his brothers were in the trucking business from the early 40's until the 90's and I don't remember seeing many Budd wheels on Chevys maybe a GMC diesel or a Mack prior to the Kenworth's and Pete's become popular in the east/south. I think out west the Budd wheels were more popular and seen more often.
