where to buy GWS servo parts?

[cummins driver]

I have a metal geared, ball bearinged GWS servo. I didnt have it long before the case on the top broke the tabs off, but the servo seemed good, and had more torque than my stock traxxas one for sure, and metal gears, and ball bearings are always a good thing too. Anyway. I was wondering if any of you knew where i could get GWS servo parts. Like i said, all i need is the top cover, and i would like to get this servo back to working. Any help is appreciated. Thanks
