model A rear tailpan fillers, part number? name?

[1948]

hello, im looking for these little flat steel "welting" strips that were in between my rear pan and the rear quarters below the trunk. the bolts for the pan went through them into the quarters. mine were lost at some point, and im not even sure if they were stock? did they have them, because i cant seem to find them anywhere! im thinking the fender welting is going to look pretty silly there. or is this one of those items im only going to find at a swap meet?
