Helping a widow dispose of her late husband's reloading stuff. There is an ancient Dillon RL450, so old that it has a serial number on a plate on the frame. The fourth reloading die hole has a buggered up thread. The press can be used as-is unless the caliber calls for having a die in that fourth hole, in which case a die will not screw in. I know one might send it to Dillon and maybe they'd replace the frame, but it's neat to have one with a serial number. Is there a tool or die that can be used to unbugger 7/8x14 threads? (not that I'd have the mechanical expertise to use such a tool). This is a hole in the frame that the reloading die screws into. This old Dillon does not use the removable die plate like the new Dillons use.
Thank you
