I feel for you Steve 11 months ago did the same job, I have the same battery but had to mount it on its side and make a new tray and retaining clamp, i have permanently attached the Ctek comfort lead so that it comes out at the side of the carpet behind me, this is going well but the battery experts advised getting a bigger Ctek (10 amp ) otherwise in bulk the battery doesnt quite get what it needs, I have checked this with my marine and aero contacts and it is true -though many of the battery sellers wont tell you this. I only put it on charge if I havent been for a drive in over a month, which seems to be fine.
