Someone did something to my rear tires and I had 2 blow outs. The axle to rod joint centerline is the only measurement I hadn't taken yet and my brackets are toast. I was thinking 2 11/16 to 3" but am not sure. Curse me for not writing it down. Can anyone help, please? I will pay 2x the price plus moneyy conversion and duty to ship to Canada because they won't ship USPS. That is why I want to build my own.
