I wanted the wheels to fit outside the bed but the kit axle wasn't wide enough.
So I glued some plastic rods inside the wheels.
And cut them down to the width I needed and drilled them out to accept the axle.
Now they clear the inner bed sides.
Im going to be moving soon, so their probably won't be any more updates for a while, hopefully this mockup with the wheels and tires will hold you guys over for a while.
