I have a 1966 Cessna 172G and some replacement plastics from Vantage
Plastics. There are a number of missiong screws on the existing interior,
and the perfectionist in me is wanting to replace them along with the
plastics. Can anyone out there recommend the screw sizes that are typically
used for a Cessna interior? Vantage sells quantities of stainless screws and
washers, but I would like to either get a kit or minimize the number of
different screws that I have to order.

TIA,

Typically #4 x 3/8" or so, but you might also find #6 and #8
screws. They are driven into the aluminum itself rather than anchor
nuts, and as the holes wallow out they are usually replaced with
bigger screws. Cheap setup. And to do the annual/200 hour inspections
you have to remove the interior stuff, which just tears those holes to
bits over the average airplane lifetime if you do the maintenance
properly. I wish Velcro had been available when they designed the
airplane.
