I am placing a bolt order and noticed that amk lists a different alt bolt and spacer kit for 440-6 engines c-8141 with 6 pieces, vs c-8140 for 383-440 4v with 8 pieces. Never knew there was any difference 6bbl to 4bbl, anybody know or have a amk catalog pic? Tried to find pic on their site but could not. My original stuff looks to be 8 pieces plus the one sems bolt for the alternator. 70 superbird 440-6 if the car matters at all.
