I bought a remote mirror and set of tail light lens from Mustangs Unlimited a couple years ago.
The mirror was supposed to be concourse, maybe it was packaged wrong, but it looked like it was made of chromed plastic, and you could see what looked like brush marks in it. Sent it back, they could not confirm if it was the typical 'best' mirror or not, so I got one from Year One. It is fine.
If that ain't bad enough, the lens, instead of FOMOCO, actually was stamped MOFOCO. MOFOCO? No copy write infringed there. They could not explain how they could sell a part like that.
What's your story?
