I found a fiberglass fender on BMIcarts.com and I am modifying it to look more like a Rupp Roadster 2 fender. I cut it down to just over 25 inches long from the original 28.5 inches. I also removed the rear shaped fender edge and using my front fender recreated the same shape which looks just like the Rupp rear fender pictures. Does anyone have the dimensions of the chain cutout for the fender? How long and how deep it is? As well as the exact locations of the mounting holes for the fender. If done correctly I feel this would be a great inexpensive alternative to a steel used Rupp Roadster 2 fender. Just about every Rupp fender I find is either rusted terribly or dented and has cracks.
