Hi all, new to the forum and wondered if anyone can help. I'm replacing the rear shocks on my 2001 (MK1) Focus 1.8 TDDI hatch and seem to have every socket and ring spanner except the one that fits. could you tell me the size of the nut which secures the bottom end of the shock to the knuckle. Thanks for any info

Anyone?

Okay, according to Rapid Fit, it's somewhere between a 15mm and 18mm and a real swine to get out because the bolt has a habit of seizing into the bush
