There is a chrome plating business in StL that used to specialize in restoring and rechroming pot metal.  It involves stripping it down, and then grinding out the abcesses much like a dentist, and then soldering and smoothing before the replating.  Do those inserts come out?  If they don't, it seems it would take a special, special artist to be able to refurb them.  He said It wouldnt be cheap, because of all the labor involved.  They quoted me 325 to do my Galaxie front bumper, but its been a while ago.  I had also talked to him about doing my quarter pillar mouldings, and thats when he explained the process.  He told me I would probably be much better off finding a used set somewhere.   Which is what I eventually did.  I have two nice sets I got off ebay real cheap, because those pillar mouldings were specific to 4 door hardtops.    Ive spent years searching for better rear windows w/ no luck. Those lower frames are the same type of potish metal that bubbles.  IF the car were a two door, or used to belong to George Jones or something, Id most likely have those window frames repaired.  

I don't think you're going to find a reproduction of those. Refurb is the only option - and I would guess you're talking big bucks. I priced having mine done about 20 years ago, and the chrome place wanted $220.00 each to plate them.

There's a huge place here in Salt Lake City Utah that's does the replating processes. They actually do all of kin digs chrome for his rides.
