err, differential I mean. As my H code 351c has 4v heads, 4 bbl intake and who knows what else I am now looking at the rear. I have read (on the internet so it must be true!1) that the easiest way to tell the difference between an 8" rear and a 9" is that the two lower bolts, at 6 o'clock and 7 o'clock need to be removed with a wrench as a socket head will not fit straight on. if that is true I think I have a 9" rear????? I know that I have posi as I leave 2 foot prints when I punch her and while the Marti report shows a standard 2.75 it feels much more to me then that gear wise. I assume a 9" is more desirable?
