Frame numbers inquiry

When cleaning the left rear frame rail after gutting the suspension for replacement, I was able to better decipher the factory numbers etched into it.


The top number was 6263668 which I know corresponds to the convertible frame p/n but I don't know if the code under it refers to a build date or some other production count - numbers are spaced apart somewhat and they don't match my vin.


4 12 72 1


The protect-o-plate is dated 6/15/72 which I presume is the original sale date to it's first owner, so it could make sense I guess if this code corresponded to the frame build date.


Is there decode info anywhere to check this?


thanks

would 4 12 72 be date of the frame was manufactured? Look on the frame where the drivers door would be. There will be a number that corresponds to the last part of your vin (or is it the sequence number can't remember) on the outside vertical piece of the frame.

Makes sense then - that would be the right time line for it.


thanks!
