The problem is, even if you spent big on NOS, plus shipping, you probably need both lens and base. Otherwise, which is oversize and which is undersize?! I don't have an original used piece to even test with the repro parts to get an idea. All I know is that they sell thousands of these things and no one seems to question that they don't even go together. I'd be embarrassed as a shop owner to stock it or pretend to act dumb like I was completely unaware. Just crazy. It hasn't changed in the nearly 20 years I've had the car, had a loose and rattly lens on it, bought replacements several times over the years, from different sellers claiming theirs was the good type. Nope, all the same, all selling lies and knowing it.
