Check out Dantes. I've been looking to get one from him. He carries the rubber ones not those cheap vinyl things and the prices are not much different.
I don't know about ready to race for that money but you can probably get a decent roller. If you are ready to step up to a real finished car for $25K let me know.
I just installed a 43 tooth in my car set up with a 4:56 rear end and running 28.5" tires. Seemed spot on calibration wise - until my cable melted on the header....
Did you determine that mine would not fit?? The rear tires were 275/60x15s on 8" Weld Draglites. Link to the ad below. I am located in NC.

There's another fellow over there selling two 62' drivers. If he's looking to build something similar to my car he would be far ahead to buy mine than to build it himself. This car has all of the best components in it already.
Have you checked Ebay? I just bought a 43 tooth gear and the lower count gears were readily available for as little as $15-$18. I had to pay $39 for mine from PATC since these are more scarce and not an OEM tooth count.
The cheap flat ones are available at any parts store like Autozone, Advance etc. Just make sure you get the right length pin for your application. Some are shorter than others.
Those are the nice ones, wish I could find them too. I wound up using the cheap flat sheet rounds with a rubber gasket underneath on mine. If you locate some let me know where!
