There is a knack to it, first side was a right b@stard to do. Second time did better, I used a small screw driver to pull spring up if I remember right.
You're right Tunnie , the first side was tears and tantrums the second side was easier but still awkward. Fortunately I bought a new fitting kit which allowed me to straighten out and cut one of the original springs which became a great puller to attach the new springs to the shoes. I also found a tie down strap handy for keeping all in place until the springs were attached a great help.
There's little difference between the Omega and my E24 BMW but the close proximity of the hub on the Omega makes it so much more difficult.
Anyway, I've had a glass of Lagavulin and it all seems a distant and minor memory now.
