if they are the new 60,000v cops that gms then you shouldnt need the spacers. if there the first ones they came out with than i would call them and see if they will replace them with the new ones. i believe they changed there tooling and made them where they fit on without the spacer. http://www.modularfords.com/forums/...t-coils-are-shipping-within-a-week-69754.html
