Anyone know where to get a 1" wood/phenolic spacer for the 850 ThermoQuad?

I have seen a phenolic spacer from Wilson for spreadbore carbs on ebay but it is pricey and a thinner one.A search on ebay should yield too many results lol.You can always mill/modify them a little bigger depending on the material.
I think I have a plastic one inch one in the barn.
