I believe the parts from a '97-'04 F-150 4x4 with 4.2l V6(same bolt pattern as 5.0l) would be your best bet.
They used the M5OD-R2 manual, a heavy duty version of your R1, it also came with optional manual BW4406 transfer case, R2 shifter is only about 2" difference from R1, not sure on the transfer case shifter.
The BW4406 is wider than the BW13xx in your Ranger, but will fit, best method seems to be moving the engine/trans/transfer case over 1/2" to the right.
There are a few "how-tos" on the M5OD-R2 and BW4406 going into Rangers.
