Today tried to do a front spring on the z3 for mot got the old one off no bother, them putting the new one on used a load of spring compressors, and got the to back on but the bottom rubber has moved and it's not sitting properly. Really don't want to take the top off the shock again so thought I'll put it back on car and limp to garage for them to do it. And couldn't get the locating dowel at the bottom of the shock to go in so couldn't get it to bolt up. So put tools away come in house
