Wilwood uses 1/8" -27 for all their stuff. So you need a metric female(10mm x 1.0 I think) to male 1/8 pipe thread adapter.
If you do the AN flex hoses, they are AN-3 usually and they have adapters on the ends. Some guys will tell you that they must be done with no adapters but they work fine. You can get hoses in any length you need, I used Pegasus Racing. They also have any adapter you could possibly want. Pipe thread, male/female, bubble, 45s, 90s, banjo ends, all of it.
