[TR] Paper TR2 Parts

[John Gillis]

I have never heard mention or seen in any catalogue the strange  
material that looks like a stick of twisted paper that sits in a  
channel behind the B post and is held in place my tabs from the  
bodywork. Its function (i guess) is to to hold the forward line of  
screws of the side trim panel and door rear seal. Why did Triumph  
choose this material, when a slip of wood would surely be more  
effective, particularly as there is timber-work in the car anyway. I  
have replaced mine, as "the paper" no longer held the screws, with a  
slip of softwood. Anyone know what it actually is?
