c7 valve cover riser bolts???

Hi we need to replace some valve cover spacer to block bolts on a C7.  The old ones had an integral bushing and sleeve and Foley cat keeps sending me a bolt with no bushings or anything.  Was there a design change on the bolt?  Noone can seem to figure this out.   The hole in the bottom valve cover is like half inch diameter so a regular 8mm bolt wont even fasten the thing down, and using a bolt with a washer seems suspect since there are no locating pins or anything to center the cover.
