Dual wheel inserts

[Bumble_Bee]

I am looking for the dual wheel inserts that go between the tires. I have the two sets of tires I just need the inserts.

Those can be made pretty easy, just measure the diameter of the rim starting at the point just on the inside of the lip of the rim where the bead of the tire is on the other side. Then hold a strat edge on the side of the tire and measure the distance from the rim to the strat edge. take that measurement times 3 and that's the width of the ring needed. If you don't want that much space between the tires, take it times 2 or 2.5 . The bolts can be made of allthread with nuts and washers on both ends. Hope this helps.
