Magura Raceline rim brakes - set-up question

[Surestick Malone]

I have a set of Magura Raceline brakes (The fluorescent green ones). They were mounted so that they weren't pointing straight at the rim braking surface and I'm trying to correct the set-up but I'm having problems getting the little L shaped arm that hooks around the seat-stay out of the piece that clamps the actual brake.

Does anybody have any tricks?
Failing that are pieces still available for these from Magura?
