Has anyone had experience with Quick Performance rear ends? They make 9" Ford rear ends that bolt into a G Body. I am considering using one of these for my 84 Grand Prix. Their prices don't seem too bad. I need a posi rear and I figured no sense in shelling out $$$ on a 7.5". I have copied the link to their site below.
