Side moulding mystery??

[DukeRimmer]

I don't know much about mechanic work and even less about performance and racing, but I have retired from the body repair biz, and am disturbed when I can not answer a 2002 body question. Our friend Jose from Las Vegas (don't know his forum name) presented one of these questions. He wants to put his original side mouldings back on his '67. These mouldings appear identical to newer type when installed, but used 12mm round clips. The modern clips we're all used to are 9mm double fork clips. I searched six different catalogs from moulding clip suppliers and found nothing that will work. Someone clearly found replacements at some time because Jose says his old clips are not round. Any ideas??

These are upper side mouldings (near door handle), sometimes incorrectly called belt mouldings.
