Goint to 8" rear wheels how many?

Going to 8" rear wheels how many?

Putting in an edge skid, going to go from 121 to 136 and then offset it to use a 144" track.

Going to put in the 8" rear wheel kit while im in there, now the question is how many wheels?

I have one axle set up for 3 and one setup for 4, but I have also seen some kits that only use two wheel which should be easy enough to do using the 4 wheel axel and just droppng off the two outer wheels...

So...
2?
3?
4?

Thanks!
