Bike Forums - Quick Click Fixer

I've tried working with this but the attachment has too much up angle to work. If it was slightly longer it could possibly work, but I'm not sure of other issues. Ideally I'd like a fixer that has 0 degree to it & be made from one piece rather than the plastic having a metal drum inserted in it.
If I could find a seat rail adapter that drops the mounting points down, that would work, but I have not found such seat rail adapters to exist.

Any solutions that would accept the topeak quickclick as shown?
