I found this on Amazon and bought it. I will give it a full review as soon as it arrives. It is a simple thing anybody could build but, for $99, I think it is worth it. https://www.amazon.com/gp/product/B075HKV356/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 This could work OK, if it was sturdier. https://www.amazon.com/Wheel-Offset...12940007&sr=8-1&keywords=wheel+backspace+tool I looked at the $300-$500 (for a couple pieces of metal) then at the Percy's Wheel Rite (you do not make tools out of plastic)for $79. I think this one will work OK.
