UMX Timber Wheel Stops and Dubro Wheel Axle Insert

I lost a wheel stop for my UMX Timber and decided to make my own. I also didn't like the look of the stock tires so I purchased a set of really light Dubro bush wheels. They needed inserts to fit on the Timber's small axles, so I made a couple different styles. One is a full insert that goes from one side to the other. The other set are two inserts that that goes in each side.
I also made a regular set of wheel stops and a set with a flange on one end to keep the wheel in place.
