door handle/window crank escutcheons for a '63 Valiant
For others or after Al's stash depletes,
DMT sells a flat version. I don't know if the ID and OD are correct for all applications, but a quick call will get you that info.
Mopar B Body 66-67 Charger Window Crank Handle FLAT Anti-Abrasion Escutcheon Spacers 2Pcs
Interestingly...
My one family 67 Dart has flat ones on all 4 window cranks.
Also if you don't mind white / clear, milk carton is a good substitute.
