Grasshopper and Hornet are about the only Tamiya buggies I know! An untouched original would be nice. sjhupp . Well, being NiMH anything with a Tamiya plug should be the same footprint if they're the same cells and config (unlike lipo pouches, that are just all over the place size wise) , so just search ' 7.2v tamiya plug' and check the dimensions . No idea on brands sorry.
