Yeah, beacause of some of the clones, there are some very non-standard gearsets floating around. Mostly from cars that are non-standard in the motor mount area.

I also would like to collect all the gearsets.
I'm missing the green 3.43:1 set and of course your "mystery set", but hopefully this weekend I'll be getting the 3.43:1 with one of the last two KITT racers I have stashed!

I haven't really played with the KIT gearsets with a dual cell. I tried to use them a while ago, but a single cell car just doesn't get 'em going very fast.
The wheels themselves however are killer. My first four KITT rears were broken up to either receive MS gearsets, or to be made into fronts!

I just made a dedicated dual cell charger for my cars so I have to trim the KIT rears up and see what a dual cell does with them.
