Without the fender tag giving the spd you can only estimate it comparing yours to another sequence number that's close.

On my 68 Coronet, the build date code is on the bottom of the radiator support. I don't recall when the date clock started, but I researched it at the time, and mine (1928) translated into a July 10, 1968 build date... just before Lynch Road started to re-tool for the 69 model year.

It doesn't. You aren't going to get any build date info out of the VIN number unless you just happen find someone who has a VIN a couple digits away from yours that was built at the same plant. And that' a needle in a haystack.

My apologies... the four digit build date code is on the K-frame, not the radiator support. My mistake; I suffer from CRS.

So upon further research, my K-frame code of "1928" means the car was assembled on the 192nd day of 1968... July 10.

Do you know your SPD from the tag or other document?

Unfortunately, I have zero documentation: no fender tag, no build sheet, no certicard.

But that fact gave me the freedom to turn her from this...

To this...
