I read that it only affects the 2000-2006 models.

Because nobody would ever steal a 1999 F-350 as they are such different trucks.

Also, the article says there are an estimated 2200 trucks affected... I suspect it's just the F-250/F-350 and not the F-150 (which I think already has a PATS or something).
