Kube….I'm gonna show my possible dumbness here, or at least some long-term memory loss, but do all '40s have that double "hole/slot" at every fender bolt location (as seen in your pic) or is that something you possibly dreamed-up to aid in perfectly aligning the fenders to the requisite "Kubarth Standard"? That's gonna be another "sweetie" straight out of Wisconsin. DD
