I've bought a Wald 137 and I'm thinking of mounting my dynamo light on the front with a P-clamp. How bad of an idea is that? My local hardware store sells these with a nut on them, I'm thinking I'll clamp this onto the upper rail flip the mount on my light. See attached sketch (probably not to scale).
In the past I've made a light mount a piece of steerer and a star nut.
However in your case, I would use a disc brake mount spacer and attach it to where ever you want on the strut. I've done this on a few bikes, its rock solid and gives you good adustablity for setting the angle
