Hmmm...I didnt even look at them yet. This is obviously going to be a problem with our chassis, seeing as it will have a 1/2" oblong hole for chain tension.

I also wasn't going to be using 1/2" shaft, I was just gonna throw a 1/2" bolt through the oblong holes and wheels so the wheels can be quickly adjusted for chain tension. I'll be making sure 1/2" bolts fit through first thing tomorrow....

Also if you are using shaft, you could always turn it down a bit on a lathe to make it a better fit.
