Vintage 1986 Diamondback Ascent Mountain Bike Frame + Fork Tange

This frame is in good condition, I think it's a 1986 model but may be 1985 (date codes on the brakes correspond to 1985 but color was 1986 I believe). Some minor paint chips and scratches all over, but no deep rust, dents, or other structural issues. The bottom bracket and all other components came out without any drama. The headset feels a little rough, may need re-packing or replacement. The original seatpost is included, the shaft is scratched up but works properly.
Sizing:
Seat tube: 20" c-t, 18.5" c-c (I think this makes it a medium, might be a large. Help me out if you know)
Top tube: 22.5"
Headset: 1" threaded (will need a stem with a 22.2mm shaft)
Rear dropout: 126mm
