Toyota Townace Royal Lounge - Removing trim to get to relay/fuse block.

Hi

I own a 1990 Royal Lounge in which I need to replace the fusebox/relay board behind the central dashboard trim (and behind the coolbox) but cannot work out the procedure for removing the trim panels. I can get as far as removing the instrument and radio surrounds, but cannot see an obvious next step. Trial and error is not an option as I do not want to dismantle anything I don't need to or risk breakage of hard to get parts.

Any ideas?

Anybody got a junction box number 1 (see attached) they would be willing to sell me - I am in the UK but happy to pay the postage?

Thanks guys
