Would these drive cups work? And then I would need two of them right?
What about the slipper? Could I just use the stock slipper clutch?

Thanks...

Yes, those will work. Mike has them aswell. As for slippers, I would go for the Strobe slipper. That with the Ofna 51T spur and a mod1 5mm pinion would work well.

Sweet man, thanks.
