Picked up a "unique?" parts dart

The Windsor plant had F codes all there own, if anyone has discovered what they actually mean I have not heard of it yet......

G52 is the driver side chrome mirror with remote.

J42 does not compute, can you post a clear photo of the tag?

Have you searched the car for broadcast sheets yet?
Oh nice Happy birthday! Yeah i'll post a couple more pics of it. No I haven't had a chance to dig through it yet it's been pissing down rain I hope the sheet is intact.
