NEw guy question, Help needed

[blakktalon]

I got my first buggy/ first losi car. Actually two, Got a xxxbk2, and a bk roller he threw in with the package. My question is, is there any other steering knuckles/casterblocks/ arm sets that will work for converting the fronts to something other than the 10mm hex.

I would like to be able to run the same size buggy tires on the front and rear. Not only can I rotate the tires when the rears wear, I think the more surface area on the front will help with steering.

Any helpful idea's would be greatly appreciated.
