"...........My present passenger side front fender has the tire well but I've been planning on filling it. It would be much simpler to just replace it, then sell the old fender off......"

I'm kinda of at the same point with my 37 Dodge PU. From what I understand, all the PUs had the spare tire well in the fender. I have seen a couple Hot Rodded 37 PUs on E Bay over the last couple of years that are advertised as having fiberglass fenders and from the pictures, they are available without well. I haven't really looked for a source, as I'm planning on just filling mine.
