UPDATE!!!
Made the deal and brought her home a couple weeks ago. Several cases of Brakeleen, a whole lot of internet knowledge sharing (from fine folks like yourselves), an almost obsessive amount of shop time, and her she is!! Turns out it was a single-owner, 100% original (down to the air in the OG Nitto tubes), 1569 original mile, LB80IIHC. As you can see, I've added a few things, but have kept all the original parts. Used the stock intake boot to fit a pod filter inside the housing without the front of the box, MLM pipe, jetted to 95 right now, and there may be room for a tad more. It sounds like a pissed off chainsaw, will pull the front tire pretty easily and i've GPS'd it at 50mph +. What a damn riot!! Thank you all for the help!!
PS: chefhockey, I'll reach out to you for those parts if the offer still stands?
