Dale, You won't find any Chevrolet 1 1/2, or 2 ton trucks,with 6 lugs, unless they are Army trucks. Standard civilian Chevy trucks from this era, were 5 lug front, 10 lug rear. Civilian 1 1/2, & 2 ton GMC trucks from this era were the same. 400 series, & up GMC's, were spec.'d with 6 stud, or 10 stud wheels. Dayton spoke wheels were also available, on the Heavy GMC trucks.
