I used to think the same many years ago. But if one thing about crawling the yards every week for the last two years, is that those are one of the first things to be stripped from coupes. Any coupes that have them. To find them is a rare treat and I picked up my sets during the heyday of C4C. As Teutone can attest, they are rare and were very plentiful back then.Just check out some of the junkyards near you...I'm sure the seat belt extenders are rarely taken off of them.
