Np203 Gear Reduction box, Arizona Tucson

I think its a 1979 Dodge NP203, use it as a Doubler T-case 2:1 reduction, 23 spline input will mate to the AW4 or 23 spline 5speeds $100 OBO. 80Lbs

Picture of the 203 mounted up to an AW4 with a ford 205 behind it. you can drill and tap the 203 to any clocking you desire, as pictured it is upside down. would need a 203-205 adaptor or 203-d300 type adaptor. As part of the adaptor price they would cut and re-spline the ourput shaft for the seconde T-case. I payed $450 for my 203-205 doubler from Jeds machining.
