Volks, Mike and Gerald,
Thanks for the ideas. Yes, these are the seals used where the heater box outlet pipe goes through the steel body panel above the torsion bar housing. When I hold a couple of the crumbled fragments up to light, it shows that they are translucent -- probably not asbestos. But also not very durable over time, obviously. And both of my bakelite flange-and-tube assemblies were also badly granulated when I unscrewed the flanges -- they fell apart into multiple pieces. The insulated heater tubes under the rear seat are wrapped with "blankets" that feel like old-fashioned jute carpet padding, wrapped with a vinyl jacket, and held together by 15" cable ties. But the insulating material is noncombustable: it won't light with a match. I'll look around.

The bakelite body tube had a flat gasket material that's oval in shape. to match the opening in the steel firewall above the rear torsion housing. I don't what it was originally made of, but the roofing felt sounds pretty reasonable to me. Yes, it gets quite hot there, but not hot enough to melt the roofing felt, methinks......it's just a seal around the edges, not in the hot airstream, right? Just a few inches further in, the 'mufflers' under rear seat where stuffed/ wrapped with a common material, right? Mike B. ----- Original Message ----- From: "Gerald V.
