Adding something here,
Some quick searching led me to the VW heritage website.
http://www.vwheritage.com/vwh/VW-Beetle-Parts/Exhaust-Heating/Heating-System/?templateID=vwh
See item number 12. This is the red rubber seal I was talking about. Four
needed per car. It goes at each end of the big accordion hose.
Ah yes the body pipe is bakelite! Item 9.
I cant figure out item number 10. its not listed.
Asad.
