Best to work from a compatible donor to get all the parts you'll need. For your 2004, the safest years would be 2004~2006 and you MUST use a 4.0L transmission (other Ranger transmissions will not bolt up to the 4.0L). Be sure to get a 4WD or 2WD transmission to match your truck - the output shaft and extenson housing are different between the two types.
In addition to the transmission, you'd need the engine/transmission wire harness, clutch, pressure plate, flywheel, brake and clutch pedals, clutch pedal position switch, clutch master cylinder with pushrod and hydraulic lines.
You would also need the PCM from a 2004 4.0L manual truck.
The plastic trim is different on the steering column and there is a manual ignition switch blockout lever to replace the automatic's column shifter interlock. You can either swap in a complete manual column or swap all the necessary bits from column to column.
Under the dash, you’d need to remove the auto truck’s jumper and plug the harness into the clutch pedal position switch.
For a clean installation, the instrument cluster would need to have the gear indicator removed. It just gets swapped with a blanking plate from a manual truck's cluster.
Do yourself a BIG favor and replace the slave cylinder assembly with a new one. It is a time bomb on any Ranger/Explorer manual and requires that the transmission be pulled back out to change it.
To me i think it would almost be better if you were to get another truck and buy manual this time and then what ever aftermarket parts you have already bought just swap them out and with the factory in the other truck and then sell your automatic thats just my two cents....gunna be alot of time and money involved in converting it especially when you do it right you would want to do like rwenzing said and get a donor....just my two cents
