Does anyone know for sure how to decode dates on bumpers?
I've found 2 fronts with the following codes:
1 21 M6
3 3 M5
Using the sheet metal codes they would be
1st week 21st day Monroe, Mi stamping 6th shift (or year???)
3rd week 3rd Monroe, Mi stamping 5th shift (or year???)
I haven't yet found any rear bumpers with clear codes yet.
Any help is appreciated.
FYI - I'm looking for a good front and rear core for re-chrome for my April '65 K. If anyone here has some for sale please let me know.
