Yes, that was not Peugeot's finest bit of design. If the head of the long
retaining bolt had been hexagonal, the same size as the wheel nuts (so the
same wheelbrace can be used) I would have been able to exert some serious
force and worked the seized threads loose without too much problem,
especially with the application of some WD40 which I even had in the car
with me. But when the bolt has a broad hemi-cylindrical slot, it's damn-near
impossible. If they'd used a slot with vertical rather than rounded/sloping
sides, it would have been a lot better, because at least the flat end of the
wheelbrace wouldn't have been forced out of the slot. But they went and
f*cked up the design properly - no half-measures: a 100% award-winning
f*ck-up :-( Full marks to the design department - and the testing
department which should have picked up that bad design.
