Hi Ken,
The additional information you provided was helpful for me to understand what you were looking for. I don’t know if this will be helpful, but when I started amusement device inspections sometime in early 2000 ish, I was provided with a few CD’s with a huge number of manufacturer’s documentation (this would have been through NAARSO). I don’t remember what I did with those CDs, but I cannot find them now. It’s possible that someone else here in VA (or even NAARSO) actually kept those same CDs and can review them to see if they contain King ride information. Wishin’ I’d kept those CDs now 🙂
