3) Seat belts: The seat belt hardware is attractive and in good shape, but
the fabric is faded and starting to fray in a few places. Does anyone just
sell replacement material for the belts? All I've seen in the catalogs are
whole assemblies including hardware.

I believe Aircraft Spruce sells the webbing, but I don't have a Spruce
catalog at hand.

The aforementioned Chief Aircraft store will reweb your seatbelts. They
have several colors available, I chose navy blue.

Welcome to aircraft ownership! And by all means get as involved as you
can with the maintenance (right Jim?)
