I would always advocate rechroming over repop.  Its hard to find shops in the US due to all the environmental restrictions.  There's still a couple good ones out there though.  One thing to specify is that you want "show chrome".  Shops tend to take more time and provide a better result if you specify its for a show car.  The cost will likely go up as well, but the quality and durability will also be better.  Remember chrome is clear.  The shiny metal color is actually nickel.  The chrome just protects the nickel.  The cheap stuff I think uses a single dip in the chrome, but the good stuff is billed as "triple chrome plated".

Explains the process a bit better.  The chrome layer isn't completely clear, but its not opaque either; its translucent.  It affects the way the nickle below is perceived, but most of what you see is still the nickel. 
 

Contacted a chrome shop here in Florida.  They are $275 per cent window frame.   Sadly they have a four month turnaround time.   Door handles are $95 each.  I should have started this process a long time ago. I’ll check a few other places and see what other options I have.

What about powder coating them in say "smoke chrome".

 
I’ve thought about doing that to all the trim.

I would be most concerned about the drip rail.  The only thing I'd worry about on the vent frames would be the thickness of the powder coat v.s chrome.  I also don't know if powder coating would be cheaper than chrome depending on the amount of prep involved.  Pits, etc. need to be filled prior to coating and you can only use certain types of filler.  If it were me I'd just bite the bullet and get them rechromed.  Its a one time expense, and its a know quantity. 

I don't know about the earlier frames, but on the '67 ones there was one part that wasn't available, basically forcing you to buy the entire vent window assembly rather than piece them together (which was otherwise cheaper and allowed you to use the correct date coded glass).  Personally I'd just wait and use the rechromed originals.  I look at it this way: its taken how long to get the car to the point its at now?  What's another month?  I also really, really hate doing things twice.  Especially on a freshly painted car. 

Cool, let us know where you sent them and how they turn out.  Most of us can probably use a good chrome shop.

The shop is in CA.   My uncle gave me the shop owners cell phone number and that’s how I’ve been communicating with him.  Funny, but I don’t know the shop name, well not yet.

Parts finally got shipped out.  Work has been super busy but we always are this time of year with all the snow birds here in SWFL.   

Shop owner claims a two week turn around. Praying I’ll have them back in three weeks from now.  When I spoke to the owner he went into great detail on the challenges of rechroming that type of metal.  So it sounds like he has the experience to get the job done right.

Probably a good move. I look forward to hearing how the re-chrome process goes and the reassembly with the new rubbers.
I went with the reproductions on mine and they don't fit as well as the originals (see my post), but I will live with it.
I kept my original vent windows and put them away for future.

I think I’m still below the cost of replacements in parts and chrome costs but if you add my time then one could say it cost more to go this route. But building them isn’t a cost factor.   I have $550 in chrome work and shipping fees.  That’s from FL to CA and back. 

I do need to replace one vent window.  I notice the little pivot piece is loose from its frame.

I think you'll be glad you went to the trouble, Bob.  I know I am glad I did.  Now you can try out those rivet sets.

RTM can you share the name and number of the chrome shop I want to get my bummpers done. I have 3 to do.
