Convert CAT K1 pins to hex?

[Nitrius]

So i want to be able to use hex wheels on the CAT K1, got the TLR 22 as my 2wd car, and would be very nice if they could share rear wheels.

Since the CAT K1 already comes with hex adapter for the front, i can use those for the front(?), but i guess only certain front wheels will work, like the "old" losi 4wd fronts?

But what is needed for the rear to run hex wheels? Preferably the tlr 22 rear wheels, if that's possible?

I've read through the CAT K1 threads, and most seems to be mentioning the B44 front and rear hex set, these should work? If so, anyone got the part number for them?

I bought the hex wheel adapters from jconcept, both rear and front, but they don't seem to fit, or they fit, but when screwing on the lock nut to hold the wheel, it doesn't get all that much thread, so i guess it won't hold for long, they seem to build out to much. But maybe that's okay, or?
