As I mentioned Ralph or RCIGN can and will make what your looking for, $15.00 out of g-10 fiberglass.

I would stay away from the metal adaptors. Plastic, Teflon, Phenolic, Resin cast, fiberglass or even Durlon will work well, insulating the carb from heat migration is desired...

I suspect the Zenoah G45 adaptor will work...
