I just baught a set of allparts solid shaft knobs and it doesnt fit over the solid shaft. This kind of sucks, now i have to drive 20 minutes to return these knobs. Anybody have any extras they are willing to sell? They are the third ones down on this page. http://www.allparts.com/categories.php?cat_id=555&cat_name=METAL KNOBS What i dont get is it specifically states "Fits USA solid shafts" ***!!!
