Thanks guys. I tried Brownells and they used to have something that would work but it is discontinued( a rear screw that was threaded almost all the way up. It would have to be shortened but would work). If nothing else I will see if I can get someone to thread a rear guard screw up as far as the front one is and cut it off 3/16 inch longer then the normal front screw. Dress the cut up and it should work. Or maybe a screw with the correct threads can be found even if the head had to be made to fit. I will keep looking.
