Been a while and I caught up on some of the later made posts, so here is my light weight suggestion. Cast you own outside door handles from aluminum and polish them up and clear coat them so they have that older worn chrome look. Also if I remember right some of the later model outside door buttons were plastic that were chromed? However late model trucks used a black plastic button that I'm sure could also be massage too work. With your car being black I doubt few people would notice the difference.
