Just replaced my sidelights for LED, as one had blown.
It was quite fiddly but my main issue was the 2 bolts joining the bumper to the wheel arch liner were corroded and stuck to the clips which then just span round.
One side actually only had one bolt, as the other was missing as part of the wheel liner missing, so a bit of a mess underneath but not bad enough any of it to be loose.
maybe this is common due to age, i've sprayed WD on the bolts, and will probably try and replace the ones i can.
I have not tried removing the other bolts under the bumper, but i have a feeling they might be a bugger to get off.
Anyone else had this issue, as i need to get bumper off at some point to fit my new mesh
Cheers
