Thanks for posting this Owen ! There was a question on the Forum earlier this Summer asking for exactly this kind of info, and I've been wanting to rig a sign like this on my A1 for our American Legion post's parades. I agree about the bolts... very little clearance between the rim holes and the spare tire mount. And I think I'll increase the diameter to 17" to fit out to the lip of the rim. Thanks again.
Support our troops, past and present.
