As for "granny" first gear; It depends on the differential gearing and tire size somewhat whether a 4.56 gear feels like a "granny". With 3.07 and 31"(or larger) tires one could easily use it as a normal 1st. Mine has 3.73 rear and I usually start in 2nd unless I'm loaded down or on an incline. So it is sort of a granny in my case. But I can still go 0-26 MPH in 1st if I want to. -BA

Eric Johnson, that's cool that you have the original build sheet. Mine is long gone and there was never even a SPID in the glove box.

Yes. Fortunate to have it!

Don't know what my first ratio is, but first is way to low to use in normal driving. Very low and whines. Reverse is super low as well. Very similar...
