I want to add a locker differential to the moonhawk. After much trial and error, I have a jbeam file in two seperate locations, both vehicles/moonhawk and vehicles/myHawk. I have tried both independently. I still can't see it in the parts selector. I'm sure I'm missing something silly. What do I need to add? My guess is that I need to add another file, but I'm not sure what file, or what it would contain. Or possibly a name mismatch somewhere. Thanks!
