I'm due for an oil change so I think I'll take a tape measure down there with me and see where the shifters will land and how much work I'd have to do to get the 3.91 first gear.
TRk:

To the best of my knowledge you are correct on the ratios. With a 3.07 final drive ratio, the .8 overdrive yields a 2.46:1 5th gear, and a 3.91 x 3.07 gives a 12:1 1st gear. Quite friendly (4.89:1 ratio spread).
