Gen3 Coupe Rear Caliper Banjo Bolt Spec

[petepetrolhead]

I didn't receive the banjo bolts (or the flexible hoses!) for the rear brake calipers of my Gen3 coupe complete kit. I have the standard calipers - not Wilwood. I need the spec for the banjo bolts which I'm trying to source in the UK. The thread measures as M10 x 1.5mm (coarse) but I don't know the length - can anyone help? Thanks!

With no information to go on, I tried a 25mm bolt (length below the head) but this was very close to bottoming out and I was worried it might not fully crush the copper washers. So I've gone for 24mm bolts which seem to be OK.
