take yours off and photograph it and send that pic above in with it to the supplier and tell them they have an error on their part system and you want a refund/replacement
Sounds like a good idea, there wont be much scope for them to grumble if there is photo evidence lol.
to be fair from what ive read ecp are okay on returns anyway.
was looking forward to doing the bushes aswell, looks like im only doing balljoints now. tomorrow is going to be a very brief encounter on the ramps
many motor factors in newport, iow called up the same part. correct me if im wrong, but where mine is a non cup with packs (it is.. 60mm on a vernier doesnt lie), maybe the arb is cup but the parts system only see's the car as a 182? (cup and packed ones run stiffer/different arb right!?) i dont know im guessing at this point....
