Just out of curiousity, does your Holley look like mine? I know of someone in Colorado that specialises in rebuilding Q-Jets, but I don't know if he still does Holley'*. If you don't have any luck I can try to find his email address if you'd like.
It can't be hard to rebuild yourself. People complain about the Qjets being hard to work on, but I rebuilt mine last year and it was simple. I didn't do anything to it other than clean it and put in new parts from the kit, but it was easy.
