Seal seems fine. Online parts company said needed a part #AP186876~ a hinge
spacer. Seeing how the freezer is about 34 years old I'm being realistically
optimistic this could be the fix we need however the part has been
discontinued/ none of our local parts stores seem to have it.

I think without seeing this it's going to be very hard for anyone to
give advice. Is there evidence of a bad/missing spacer? What's on
the other hinge, or other door, etc? If a spacer broke, sounds like
it could be the problem. Or is the hinge attachment rusted and failing?
We can't see. You might be able to find a spacer that would work at
a local appliance parts store or HD has trays of various spacers,
something might work.
