Cool, thanks again for the info. I have 16" 1941 Ford wheels on the back mounted to a 1957 Ford 9", they're a different style than the front wheels which I think are from the 70's. I can't run the same hubcaps but I'd probably lose them on these bumpy Michigan roads anyways. While we're on the topic does anybody know where I can get a set of lug nuts for this 1940/1957 combo? the studs are the same all around. Thanks.
