Anyway bought one and fitted it today.
Took a few quick pics as I fitted it as they may be helpful to someone.
Essentially the lock is a two part external 'block' that attaches from inside the rear door so you dont have to drill any external holes in the panelwork - you don't need to drill any internally but I modified its fitting slightly.
I pulled the seal off the door and fitted the lock underneath but trimmed the metal 'gripper' section from the seal where it fits around the lock, this still allows a weather proof seal and gives a lower profile to the lock so it doesn't foul the closing door.
The instructions say to use the included screws to 'jack' the lock in position but I drilled the inside of the rear door and fitted 'riv-nuts' to screw the lock bracket into. There are two more screws needed so the lock cant be pried away from the door 'to get behind it' but I need get some correct length screws rather than the overly long supplied screws or I might weld a steel plate/block to the inside of the bracket.
Result seems pretty secure and will protect against 'Tibbe' double unlocking. Time will tell. The lock was £26 from Ebay.
Fitting instructions.
