Hello Guys, I have a used oem 1931-34 REAR 18" wheel on my 1931 scout 101 frame & want to get the wheel checked & trued at local shop. Is there an offset for this rear wheel? { I see for the FRONT wheel in Tech Tip section of our Shop Manual shows 1/8 - 3/16" from brake side from edge of rim ,if I am reading this correctly,but didn't find for rear wheel.} THANKS, Rex
