M-4001-88373T (rear diff)
This is part# of differential that Ford discontinued according to my info and it is the one that matches to the T-56 shifter in terms of rpm in gear etc.
I have no idea if that was ever used in Rangers. I do know it's the diff that people look for to use in the FFR Daytonas which have Mustang type rear axle and there's been quite a bit of talk where you can get them (or not) as apparently all the ones available now have to be pulled from something.
I'm not saying everyone likes that diff but by and large it's the one people look for and I don't know the reasons why but usually in situations like this I just read what most experienced people say and go with that.
It is an altogether different project just came up because of differential discussion. They are putting various engines but typically today you would want to use the Coyote/T56/Torsen 3.73. So you are running about 450HP in a 2400lb car. You can put all kind of different engines even LS if you want or Ford SB 427 etc or old rebuilt 302 or 347 etc etc. just depends what you want. Obviously at 5lbs/HP you are running basically a race car on the street.

For those not aware of it there's a great writeup here on TRS about what was available when, for the FX trucks: Ford Ranger FX4 Off-Road and Level II - By The Years - The Ranger Station
2003 FX4 L2 had 31" tires OEM. Maybe some other years too.
