Cheers guys,

So i'm guessing Ford must have stamped the smoked light lenses as well as mine have the chassis number on them in the correct place as well and exacly how the original lenses would have been stamped in fact if you did not know better you would think the lights came with the car but it coulden't have as it's 2WD.

Still interested in why some have reg numbers and other have chassis I'm pretty sure it was in 1990 it changed.
