I have not tried the Ford or trailer wheels but did use a set of 1990’s vintage Chevrolet Suburban wheels on mine running modern radials. I added clips for using the original 3/4 ton hubcaps. Both wheels will require spacers or modifications to fit the front as the back spacing interferes with the original tie-rod ends. My original set of four was purchased at a local wheel reseller.
