That's a nice finish on your hangers.
You'll regret not doing the swinging arm if you put it back together with those nice hangers and a fresh painted engine.
Check your swinging arm pivot pin for ovality, then push it through the bearings to feel for roughness or play.
I don't think there are any seals on the bearings? But there should be shims either side, between engine and arm... They should go back on the same sides as they came out.
Looking good... Keep us posted on progress...
