I would buy a 7/8-16 tap for in the 20 dollar range and run it in the 7/8-18 threaded one to change the threads. Option #2 is buy a die to change rod end threads. Can buy tap/die in either right or left hand thread. With at least an inch and a half threaded into the sleeve plus the sleeve clamp there is zero chance of it pulling apart. Never have to search for rare one in the future.
