Well, after much rummaging around, I found the two photos in the depths of my hard drive!
Picture 1
Showing how that fiddly spring that went 'boing' and across the floor actually fitted... eventually! A right PITA working that out!

Picture 2
Showing where I put some padding it to make the microswitch work. It was easier doing that than some of the 'ideas' I'd seen in other forums on replacing/fixing the wee devil - and lasted for as long as I had the car after 0 which was 3-4 years (?).

Hope it helps!
