Can anyone advise me where I can obtain decent rear quarter window rubbers - (they are different to the rubbers in the 4 door sedan).

If you're talking about the weather strip that holds the non-moveable "vent" window, the small roughly triangular piece, into the body you will have to locate one from salvage or use somekind of universal molding. The universal can be made to work but will not hold the chrome trim on these cars. If you're talking about the narrow, straight weatherstrip that seals the moveable rear window to the rear vent frame then the similar part from a mid-60s B-body will work and those are available as reproductions. They are slightly different from the original early 60s A-body piece but look as though they will work fine and it would take a sharp eye to spot the difference.

Actually, IINM new '60-'62 A-body rear quarter glass rubbers are available in Australia. See here, here, and here (some navigation required). I don't know if these repros are compatible with the '60-'61 stainless steel trim, but they're compatible with the '61-'62 chrome-look lockstrip, and the Pentastar Parts ones are supplied with the chrome-look lockstrip.

Too many people who were born on third base actually believe they've hit a triple.

Yes, I know about those, but I don't believe they will work on the hardtop and I know they aren't compatible with the stainless trim of the 62 Signet model. I'm not sure what the 61 looks like.
