I like the dually idea. Also discovered that you can buy weld in trailer spindles w/hubs. Decision comes down to matching the hub to either a car wheel or trailer wheel. These trailer hubs are 4 on 4 like a Blanton hub but I think the pilot diameter is bigger than any coulter blades I’ve seen.Something like this; of coarse I'm sure there are cheaper; but you've got a back mounting bracket, that could be U bolted around a vertical down rod from your frame, View attachment 832468
Heck, I didn't read description, but if it's a pair; then just all thread from one to the other, and run dual bare wheels? Pinching your down leg between the two sets of mounting flanges
