What are the rear end ratios by year?

A good source for specs are the original dealer brochures. You'll find them all here:

Thanks

Looks like from the brochures on Ray's site.

1959-1968 4.22:1
1969-1977 3.90:1
1978-1979 3.72:1

Never assume that a certain year car actually has that gear set. Too much swapping on these spridgets over the years. Also other gear sets were available, mine is a no longer available set of 39 teeth on the ring and 11 on the pinion for 3.55:1 ratio.

Thanks again
