... while I admit that there is a bit of ambiguity here, I do not believe
that it is safe to say that ALL V8's have 4.11 FDRs ... I will agree that
the '90 cars and the '91 5 speeds have 4.11:1, but if you came across a rear
diff from a '91 automatic it might well have a different ratio ... I haven't
looked at the '92-on cars, but I doubt that the 4.2 used the higher ratio
either ...
