An interesting bit of trivia. The door handles, hood ornament, headlight doors and tail light housings for the Carabela were all produced in Argentina as part of the agreement to source locally made parts where possible. The castings were made from US parts sent to Cordoba, however, no one thought to account for shrinkage in the sand cast so the end result is that Argentina made parts are ever so slightly smaller than their US made counterparts.
This came by way of a conversation with George Buchinger, a club member who went to Argentina in the 60s and bought a large stock of parts. When they arrived he compared some of the parts and made the discovery. He told me he checked with a Kaiser engineer and they confirmed his suspicions.
Put an NOS US 54 outside door handle next to one from Argentina and you can tell the difference. I found out when I installed a set of Argentina handles and they didn't quite fill the footprint in the paint left behind by the US version. That's when I contacted George and he told me of the difference.
