I fitted a P H to my 04 GS over a year ago and have had no clearance problems with Mic Anakees at all. If you have managed to line up the fixing holes ok then I must assume that you may have a faulty product as there is only one way to fit it.
A fellow GS owner says that he did have some clearance problems at first but was able to ease the fit gently by hand. I'm not suggesting you try this but there is a bit of give/spring in the ally support bracket that may let you see if its possible. Then cross fingers and give it some thrutch.
I had the same issue with the right side of the mich Anakee fouling on the hugger edge, I resolved by slipping in 2 more spacers/washers on the forward most bolt fixing, this gave equal clearence both sides.
