I have a set of 356 hinges (click up and click down) that I'm cleaning and polishing. I can't figure out yet how they mount. Someone on here shows an installed pic, (Scott Hansen), but I can not figure how he attached it to the firewall. I've made a comment on his pic post, no word yet. My pair wasn't very expensive around $50, others on ebay have been in the $150 range.
