The NP207 has a aluminum case and an appearance similar to the
NP231. It should have a tag on the back saying New Process Gear, Model
207. This chain driven transfer case uses a 21 spline input with the
manual transmissions and a 23 spline input with the automatic
transmissions. The output for the front driveshaft is on the drivers
side. Low range is 2.61 and high is 1.00. This transfer case is widely
scorned. If yours should break, look for a 21 spline NP231 or swap
transmission and transfer case at the same time. The transfer case is
upsidedown in the picture showing the input (it is drivers drop.)
