Were our louvers made of metal or were they abs plastic? I've seen the abs ones on ebay along with another guy making them out of aluminum.

71 B body louvers were not aluminum. They were some sort of plastic resin, not sure if it was ABS. As far as I know, Gene Gregory is the only one making correct reproductions now.
This is the last contact info I have for him (he's also on ebay)

His are probably the ones I've been seeing cause there are no other ones up for sale except his.

The Dayclona folks were making them also, but I don't see them on the new website.
