Harps

I am looking for a couple hard to find parts for my 3x2 setup.

I need a brass throttle shaft for the center carb, part#10R-5501A.

I am also looking for a couple throtle plates, part #9R-117, and also the 4 screws for these, part #5R-635.

Any information on these, or a good source for them would be greatly appreciated.

Thanks,
