Hello, all!
Also, FWIW, I’m basing my information upon the numerous pieces of original Chrysler Corp. literature which I have acquired over the years, my own research/experience with my personal vehicles, that from having assisted NJSteve with the restoration process of a number of the stellar vehicles which he brought back to life (my acronym for all of the "automotive art" which he resuscitated being M.O.P.A.R.s.” (Multiplicity Of Precious Auto Restoration successes)), and tons of research for my own cars (including over 3,500+ hours of research time in the restoration of my current ’71 Charger), which included many helpful conversations, for which I am very grateful, with Roger Gibson, Frank Badalson, Galen Govier, John Grinwald, David Wise, Terry McCann, and, tens-upon-tens more of the absolutely wonderful people in the MoPar community! (Steve’s mentioning Terry, owner of the In Violet 340 ‘Cuda, reminded me of something one of the great Canadian guys (of whom Terry is one) said while we were all hangin’ out “bench racing” & swapping stories in the evening at that ’85 MoPar Nats, which I remember as if it was yesterday. With a laugh & a smile, he said, “Here! Have a Molson! Good one, eh? Not like that cheap American stuff!”
From all of my pre-easy-access-to-the-internet days, I learned so much by talking with friends in the hobby, following connections, and, making phone calls, which resulted in my locating hundreds of correctly date-coded (now rare) NOS parts, as well as gathering information in the process, for my restoration project. Having often located stuff through relentless searching, sometimes I’m astonished, in comparison, about how little I find on the net; amongst the vast plethora of info out there. I, also, find that there is a lot of misinformation, so the last thing which I want to do is be the purveyor of something which is wrong. If you have a question about a comment I made, please don’t hesitate to comment on it, or, ask me about it
Someone who I CAN definitely recommend as a reliable source is David Wise of MMC Detroit. I have several of his amazing books. He’s totally dedicated to date code detail/accuracy, and, extensively identifying even the most obscure fasteners & hardware, and, so much more. I just looked on the net, and, although I hadn’t previously checked, I found a good “Understanding Production Date Codes” page on his site. Here’s the link.

I hope this may prove helpful!
