Has anyone been able to confirm if the single axle tire chock and leveler work with 12” wheels? My 1940ltd has 12” radial wheels. The single axle tire chock lists as having a retracted width of 10” on the bottom and 16 1/2” on top. the leveler says it’s for 13, 14 and 15” wheels… but not 12? I’ve read reviews on Amazon that state they work but would like to confirm here as well from someone that has had experience with them.
