At this point, we started crunching numbers for gearing, final drive, and crawl ratio. If you ask 6 different people, you will get 6 different answers to the best formula, so we compared our probable numbers to the owners last wheeling rig ('97 Defender 90 with 4.10's, autobox, and a supercharged 4.0 V8)
It was found that our engine, trans, transfer case ratio would not give us the needed match to the old crawl ratios.
Swapping in a 3 speed transfer would also not do the needed drop.....
