My friend will CNC machine a pair of rear catchers for me if I get him a CAD drawing or a pair to copy.
Any chance you guys want to help me? Will of course pay for your time and effort.

Before you start to call me a retard, here's the reason. They cost around 1200 bucks new over here and often 500 plus shipping and customs if I find them used here and I don't even know if they are worn out.

...and and just love custom parts...

 

so can he machine the inner "spiral" that the latches lock into.?

edit:
no matter am sitting here looking at my catches and latches there is a steel sleeve that the latches spiral into and lock..

 

Yes sir, had a way to solve it.
