Spinner bushing help Please
 

Guys,
I purchased a Pro Spin aluminum spinner to go on my Enya .45 CX. The problem is that it only came with one bushing that fits into the backplate. It is fixed in the backplate. I could remove it I think, but would need another bushing to fit inside the back plate, that would ALSO fit the shaft of the Enya 45 CX. What can be done? Does the factory sell different size bushings? This is a 2 1/4" spinner, by the way.
The only other not-so-cheap spinner I have experience with is the one that came with my World Models Spitfire. It had an aluminum back plate, and came with a four stroke and a two stroke bushing. One of them fit my FX .61 just fine. I tried to use both of these bushings on the Enya 45 and they were both too big.
I have not measured the Enya 45's shaft yet, but I will soon.
This seems like a common problem that spinner companies would have fixed by now? Is there a company that will sell me a spinner specifically made for the Enya 45's shaft? What is my best option?
P.S. Local hobby shop doesn't stock many aluminum spinners. Mostly the cheap nylon ones, and they don't seem too knowledgable with this matter.

All the spinners i have bought were either made for the specific engine OR came with 4 or 5 bushes to adapt to any engine.

you could just spin a bush up on a lathe or go to a hardware and find some plastic tube to do the job
