Right mine are either seriously stuck or im doing something wrong, 4 bolts are off, mudguard is off but the brackets just spin, no movement at all up or down. Ive tried tapping them but the plastic starts to deform before any movement....ideas???

the parts fiche shows a 'stopper ring' above them - does that indeed stop them from moving vertically??

spot on mr banoffee, electrical tape installed and all back together, hopefully the ride to cosford should be knock free from the front end
