Bruce,
Sorry about the delay on responding. I was in town most of the day. Yes, a few pics might help.
[email protected] I again spent some time looking and pondering, last night. I can see no way to raise the "arch," but that appears to be necessary...unless the ornament does not sit plumb with the hood line? I doubt that, though, as the hood stikes it when opening, if it isn't plumb or less.
According to the Filling Station catalog, the '39 and '40 are the same.
Thanks,
Gary
