Nope. I haven't damaged the ones you sent me, if i had that would mean i'd actually got the original gits out of the sod in the first place lol.
The first was a doddle, the second gave up the ghost the first time i tried to turn it and now i have something looks like a big rivet! The second is in so tight that my torx bit snapped in half! At this rate by the time i've got the bloody thing off the rest of the car will have disintegrated on the driveway lol.
Frustrating!
