One front wheel is marked with a hand stamped vertical line over the “-“, the other is not. One rear has a manual “-” rather than machine made. All have an actual backspacing of 5.25″ to the outside of the lip and are 9-11/16″ overall. Inside width is 8.75″ This indicates and offset of +10.3mm. (i.e. wheel rims moved 10.3mm inward)
