Gluing carpet to the gearbox cover

[ps4330@okc01.jccbi.gov (Peter Schauss x 2014)]

The carpet set which I got for my MGB has a separate jute pad to 
go under the section which covers the gearbox tunnel.  What is
the best way to install this?  Should I glue the pad to the tunnel and then
glue the carpet to the pad or glue the carpet and pad together first
outside of the car and then glue them both in place?

Thanks,
