[Healeys] Jute underlayment

[john spaur]

I have a Heritage interior kit for my BT7. It came with the jute 
underlayment but it is very thick. The jute is supposed to be 
installed under the seat tracks and under the wood filler and metal 
strip that goes over the tar paper or whatever material people use in 
lieu of the tar paper.

Are people installing the jute as described?

Are people cutting slots in the jute like the carpet is slotted for 
the seat runners?

Are thicker wood strips needed? Mine are 5/16" thick?

Many thanks for any guidance provided.
