Kind of on the fence about selling these, but realistically, I'm probably never going to use them. This is a set of Montgomery Ward / Gilson dual wheel adapters. They are for the standard garden tractor 12" wheel lug pattern and spacing. They are solid cast iron. They measure 10 inches from the the inboard face to the outboard face. All mounting hardware is included, even has the hard to find double studs for the inside wheel. Pretty heavy to ship, but they may fit in a large flat rate box. $150 for the set and the hardware.
