Can anyone tell me what the material is that the mid 70s Cessnas used
for the interior plastic? We have a couple of cracked pieces we would
like to repair. I also remember reading a good article in one of the
aviation mags that went through the rebuilding of a really bad
instrument panel plastic cover in the last year or so... Anybody
remember which one it was?

IIRC the plastic was called Royalite.

Royalite is a brand name, and the plastic, as far as I can
determine, is ABS (Acrylonitrile Butadiene Styrene) and can be patched
with scraps of similar stuff using the yellow ABS solvent cement
available at your hardware store or building supply; it's used for
plastic pipe connections. Don't use the white PVC pipe goop.
Small cracks can be repaired with a scrap of fiberglass cloth and
the ABS cement on the backside of the panel. A goopy filler for bigger
cracks can be made by mixing the cement with some ABS shavings from a
piece of ABS pipe or any other ABS plasic junk. Computer printers,
telephones, some toys, are just a few examples of stuff often made of
ABS. The hard plastic panels in many cars will be ABS.
