Got my coilovers today, obviously was anxious to fit them so jumped right in. Problem I've run into is the rear shocks have a different thread on them to the standard shocks, so the old top nuts don't fit. Only one of the new shocks came with a nut, so I need another. I've managed to deduce that it's an M10, but all the M10 nuts I have are a much broader thread. The nut I need is much more fine, any ideas where I could get one from? I checked at work tonight (Homebase) but we did nothing suitable..
