Bert et all,
Sorry but Im a bit grey in this area due to the fact that this part of the
world is quite warm and VW heaters are almost always disabled in my city at
least. In fact I have yet to see a bug with working heaters. Thanks to
irresponsible mechs who throw out heater parts everytime the engine is taken
off or the car goes for any work.
I did not know there were bakelite parts down there. Is it the short tube
which clears thru the body under the rear seat?? Will try to knock on the ones
in my 68 next time I pop the rear seat butt rest up. I thought they were metal.
I have seen rubber gaskits at the boneyard. I thought they went where the
big accordion pipes joined with the body with the mentioned bakelite (?) pipes.
Could this be what you are referring to?? They are bright orangish red. I think
I have seen these advertised on websites. Could this be the crumbled material
you found?? Ironically Ive always noted these to be in very good shape, even
with 40 odd years of abuse in our tropical weather and no love.
Best wishes and regards,
Asad
Karachi, Pakistan.
