RW Racing make them down to 64t spur in 48 pitch. You can pick them up on ebay pretty cheap, under $10.
They work really well, the 3racing ones and Xenon spurs tend to not sit flush, the RW ones have a recess in them that lets them sit well on the layshaft, I have stripped the layshaft hole trying to get a 3racing spur to fit.

If you are using the inside servo post check to make sure the belt isn't rubbing on the post - a friend had this problem

I had a brief run with the smokem deck last night, it steered REALLY nicely but I had a little trouble getting on the gas. It was my spare car though and I didn't have time to play around with it so I think it would be easy to sort out

If your new to the Class, I would think a 10.5 would be PLENTY enough power for a newer set of hands. Heck 13.5 boosted is pretty darn quick for the new guys.

thanks eric lee

Hi Eric. I still think that the gear diff is faster on carpet, but like on asphalt it is harder to drive. If you want your car to be easier to drive i would still consitter a ball diff but you could loose a .1 on your hot lap. I normally find 2,000 in the rear to be the best on carpet so i would start their.

Too bad xray don't have a cover for their diffs , making the ball diff vulnerable to dust !!! You can make your own cover , or bite the bullet and run a rear gear diff with front spool and front ecs drives ...Front diffs, whether gear or ball, give too many problems...
