I have a 50 Chevy truck with a Mustang II front clip. When I bought it someone had started restoration. They have some Eagle 17” wheels on it that has a 4” center to center bolt measurement. Is this an odd bolt pattern measurement? And would this be a Ford bolt pattern? I’m not sure what bolt pattern it is. Wanting to buy new wheels. (see pic)
Center to center measuring is only valid when you are measuring directly opposite holes or lugs on an even numbered lug wheel (4, 6, 8 lugs). Try measuring your odd numbered lug wheel like it shows here: How To Measure Wheel Bolt Pattern
