on the sump side you will ned to tap for the oil returns, ford did them under the oil line but the heads sometimes hold lots of oil and it needs a quicker way to come back so most put them in the front part, but this will foul the steering pipes
get a complete engine loom to the plugs
you can then splice into your pulugs if you have a 90 spec car and abve
you will need the clutch, flywheel, stater, flywheel bolts, clutch cable, pedal box from the 4x4, don't forget to threadlock the bolts for the flywheel when you fit them
the 4wd pipe up pie is different, not hte pump, so if you can change that it's enough, but make sure it's not bent and make sure you can braze it back where it goings the bit with the bolts to prevent it from slipping down the pie and cauing oil starvation issues
the rev copunter should work if you tap the correct wire, but it's a twin plug on teh bulkhead you need to get the ffed from, white plug, so if you don't have that it might be an issue
the 12v uses the coil for the revs where the 24v uses the coil pack so you need to use one of them
i'm abit dissed so it mike mate more sense in the morning
