There are gearsets available for the D20 3.15:1 and 4.86:1, The lower the T-case ratio the lower your gears in 4wd.
The NP435 and T18 are allmost identical, I know the 435 has a 6.32:1 first gear. I'm unsure about the T18

The 435 has a 6.69 1st
The T18 is 6.32
I'll keep my 435, low gears and cruise at 60-65 mph. Don't need to speed in a lifted, soft suspensioned, short wheelbased, brick shaped Bronco anyways. And that extra point gear reduction over the 4500 is more than worth it.
