Hay Dave,

This is so sad to hear.  I never had the pleasure of meeting Frank personally; but over the years had many interactions and great conversations.  He will be greatly missed.

Than a Chevy. You may be able to find a brass bowel on eBay. Just keep checking.

You should be able to straighten the brass bowl.  These cabs are hard to find in working order.  The pot metal parts swell and make them hard to disassemble without damaging the carburetor. 

The carburetor was also used on chevy of the era.  Might find some parts searching under chevy.  The chevy used different jets but the rest is the same.  I had a chevy club guy in Virginia rebuild mine.  He did a good job making one from two sets of parts which I sent him. He used the correct jets for Plymouth.  It has been some time since and I don't know if he still does these carbs.     

It doesn't look like anything there is stock parts.  Good luck with a solution.

I am only sure for the 29 Plymouth U.  It's flat glass lens.

I would suspect that the copper background is because the plating has been polished off.

Not quite sure what that is and assumed it was some type of rivet.  Possibly not on the 30U since I thought the 30u had welded frames.  Either way the hole has nothing to do with mounting the radiator.  For mounting you need the 2 threaded studs.

Talk with your radiator shop.  Given both radiators (new & old) they might be able to fabricate a solution. 

In any event someone will have to. 

That hole isn't used for mounting the radiator.  Its purpose is to accommodate for a rivet point on the front frame.

This is not the correct radiator, but it is one that was fitted to my car prior to finding an original replacement radiator.  The point being is that it mounts the same. The bottom has two threaded studs that fit into the front frame.  They are bolted to the frame with washer and nut.

The top of the radiator is attached to the firewall via two rods.

You might be missing the mounting studs.

I hope this helps, Chet
