I have seen some 60-63 using the white, usually a Custom Cab truck, but one was a std cab. It prolly boils down to whatever they had on hand that day. Just about every 63-64 I've seen had a white column, even std cabs-but my burb had a fawn column, the other 2 trucks(one std, one CC) both had white-built @St Louis, the burb was built in Cali.
