Anyone here know the nut size of the front bush on the wishbone of this vehicle? My Britool 17mm combi wouldn't go on, and I didn't have an 18mm so went and got a Torq one from B and Q, the only place open. It seems pretty shoddy quality to me, and the fit is very sloppy. I don't want to put any force on it really, I'm sure it's going to round the nut off? Is it an 18mm nut? The bolt is 15mm by the way.
