So I did last week what I really didn't want to, but had no choice. I cut a panel in the wheel pant to allow me to get the wheel off, and do the cutting & reinforcement that I needed to do. I used a balsa saw for the vertical cuts and a thin dremel cut-off wheel for the long cut. Once the wheel was out of the way, I cut off the fau-axle and started cutting the doubled up part in half so I can get my dubro axles on. I made a quick wood jig to hold the wire up and tight so it didn't move while dremeling, which is working wonderfully. Now my issue is I cant get the dremel wheel parallel to the doubled up joint to separate it. Might try my household side cutter.
