Air-Conditioning Issue Sagaris

[TVRnutcase]

We are trying to establish just where the air-conditioning in a Sagaris is leaking gas.

We have eliminated large sections - however on the N/S the pipes go under a cover on the guard.

This cover looks to be neatly sealed in place - we are trying to get under this cover. What is the method to get under this cover? Is it glued in place? Screws?

Any comments on accessing the air-con system will be much appreciated.
