There is a shop in eastern Washington that I was sent to for this but it was more expensive that new ones from Accuride so I bit the bullet and bought six new ones. I couldn’t fine any used ones either but I didn’t have the time this is a working truck. If anyone is interested I do have 6 good 10 hole X8.75 3 piece 20” wheels 2 with 70% 8.25X20” ribbed front end tires and 4 with 60% 8.25X20” traction rears mounted on them.
