Probably one of the last 1975 Dart Swingers produced

I just noticed your photo of the Mylar door sticker.

The SPD (scheduled production date) on the fender tag is 919 - BUT - The MDH code (Month, Day, Hour) of final completion on the door sticker of 082920 is over two weeks earlier.

So, more proof for the under-educated & online decoders that list the SPD as the 'build date".
