Found the nylon bits at the local hardware store. Also obtained a grommet for anti-chafing gear for the grid cap wire. Replaced a bunch of components on the power and volume switches, figured out a few differences owing to the 6J8 tube... got as far as the band switch with a rat's nest of rubber wiring and thought, "this has gone well so far... I think I'll stop and tackle that fresh tomorrow."
I figure 2-3 more hours into the chassis and I'll be ready to live dangerously and bring out the variac.

Double conversion is using two IF converters instead of one. This improves the image response.
