Anyone know the specs on the rack and pinions on the prt alpha?

anyone know what they are? I am using a 20t pinion gear looks like my y rack needs replaced and it may be faster to get it from mcmaster.

The above thread gives the pitch and pressure angles for Browning gears. Apparently Shopbot has used at least one other brand/specification of gearing, because whenever I buy new pinions from them they look in their records to see what type of gearing my machine was built with.

found the right ones but they are only .375 wide and thick the shopbot ones are .5 in each.
