sound and heat shield under bonnet of RS??

[Mysticality]

As for running engine coolant lines into the cab and under my bum, I had enough trouble fitting an extra under seat storage box that's made to go there!

Ooh! Another question!
How much room is there between the plastic BT-unit cover and the bottom of the storage box?
I've mounted my UHF receiver ontop of that, but I want some more places to put things. The glove box just isn't big enough!
