Hi I have put up some photos. The first one shows the rail what the spring with the swivel Handel is touching- you can see the rusty mark on it. The last photos are showing the seat in situ, with the front brackets lining up and the rear brackets are up in the air ( I have put a socket in one so you can see how much of a gap there is) and you can see how the spring swivel Handel thing is touching that raised up area. I can't find anywhere to hook the small spring on. I know the photos aren't the best but hopefully someone can point something out? I did try the seat with the seat base fully up and fully down, but still to no avail! Thanks for help, matt
