wanted: F15A parts

The 20" rims and 6.5 diffs are a reasonable combination although you'll find yourself shifting gears earlier on hills of course. I've found (on a Chev) that even with 12.00 20 tyres you could still do with another gear on downhill runs.
The 12.00 tyres are quite a lot larger than 11.00.

You'll have trouble shifting to low on hard surfaces unless you remove your front driveshaft (which is a good thing on road trips) or re-rig your transfer case shift with a separate front axle declutch.

Shuffling low to high in the transfer case is similar to changing gears in the crash box but the lever has a longer throw.
