After searching around for a locally made O/D unit and encountering exorbitant prices coupled with questionable strength, I had a blinding flash of insight, and I've rushed home to ask you guys this question. What about a range box from a 203 reversed and divorced, mounted behind my transfer case with a customed up yoke on the side that needs it? I don't have a 203 to tear apart and need some thoughts from those that have rebuilt them. My thinking is that I need about .7 gearing as a suitable O/D gear. Why not use the 203 range box to split third (465 3rd= 1.57) for a 'tranny' that would give approx 2000 revs at hwy speed with my 4.10 on 33's. Obviously some fabrication is required (oh my and theatrical sigh! any excuse to break out the tools) for a mounting device and/or cradle....also the yoke setup, does the range box have two male output shafts???......anybody with experience here feel free to burst my bubble, would it work?? Some things which could cause problems are....are the gears straight cut?..how would they handle running backwards?......will I be able to shift at hwy speeds? Well thats enough rambling from me, what do you think?
