I think I know what to do here... This is the stop as it currently sits.
This is where it goes when the back of the tire touches the frame.
I'm thinking I need to get some steel the same thickness as the current stop and butt weld it to the stop extending it the length I need it to be. Thoughts?
Hardest part might be deciding just how far to extend it... And the welding it well enough so it doesn't break off of course...
