Some previous owner of my car decided the transmission tunnel was not big enough for their shifter and butchered it. I cut up an old front valence for some sheet metal and patched it. I have never welded sheet metal on a car except in practice. Thanks to all the restoration shows I watch for technique. We won't discuss all the grinding to make it look good.
There is a trim ring on the bottom side of the shifter hole. Is that part reproduced? I have no way of making that unless I step up to 1/4" bar stock (might make it better, who knows?).
