Heres my 1984 Miyata 610. The only original parts are the Wheelset (Sealed Bearing Suntour Hubs), Seatpost and Rear Rack. The rest of the build is mostly period correct-ish, plus newer cockpit. I moved a majority of the original parts to another bike ('85 Sekai 2500) and built up the 610 closer to Miyata 1000 specs.
