To make matters worse, though the BOP is supposed to be B-O-P, some of it does not apply to Our Birds, because there were no "B" and "O" F-bodies. I have read stuff about Olds 10 bolt rear ends that might be true about Olds, but are wrong when applied to Pontiac. (Don't even get me started about the Olds 12 bolt 10 bolt rear end.)
And, Salmon - you are right. Your information is probably the most accurate. I was trying to find a back-up source. Of course, as you and Scott also correctly point out, unless you have "real" experience, the information in the books might not be worth the paper it's printed on.
