This is the last update to this post, I'll try and be more regular on here now that I'm getting more time to work on the car.
I did manage to score some more NOS parts over the summer as well, important ones at that!
This muffler popped up on ebay out of nowhere, so I jumped on it. It's OEM and correct for wagons, I'm stoked!
I also scored these front seat belts, the rusty ones were what I was working with on my car. The shiny ones came all the way from England; they had been removed from an FF-1 in the early 80's when GB changed their seatbelt laws and required shoulder belts. The PO tucked them away in a closet for 38 years! He posted about them on Facebook, where I contacted him and made a deal. They will really bring the interior together, and are in PERFECT condition!
That's all for now, I'll try and take lots of pictures of the subframe work, it'll be a bunch of work but totally worth it. Happy November!
