Ranger 4cyl 4x4s were not all that common but were made up until about 1997 using the 2.3l Lima engine.
You have the 2.5L Lima engine so trans(M5OD-R1, 4WD) from 2.3l Lima will bolt to it.
I think you may be able to convert your 2WD M5OD to 4WD with new output shaft and tail housing but never done that myself, so can't say for sure, but stock 4WD trans is available for the 2.5l Lima, manual or automatic, from a 2.3l Lima 4x4 Ranger.
Just as a heads up, Rangers got the new 2.3l Duratec engine in 2001/02 model year, no relation to the Lima engines, so a trans from a 2.3l Duratec won't fit 2.5l Lima, but I don't think there was a 4x4 Duratec in any case
Transfer case would be BW1354(or older 1350), from any Ranger 4x4, manual would be best to find but hard to find, lol.
Adding the 4WD electric shift is not hard but.............they are not that reliable long term.
Not sure on adding front axle, you may need different oil pan and oil pump pickup from 2.3l 4WD, never looked into that.
As long as front axle ratio matches rear axle ratio you can use whichever you can get at a good price, use manual hubs
