That is really interesting about the 726 beginning S.O. number. Does that always indicate a Chrysler Corp use vehicle in 68?

I vaguely remember someone mentioning a "Exterminator GTX" promotional car, but it was before we bought the car so I didn't pay any attention to it, and I also maybe dreaming that statement

I attached a picture of the fender tag if that helps with any decoding.


I understand the 69 and up codes, but the 68 and down are very different and there is not as much information out there as the later cars from what I've found.

Thank you for all the input, this is really interesting. I welcome all comments. Would love to know the cars complete history
