So I need to find 3.9 CW and P gears from a current prado for the rear and a complete front diff assembly with 3.9 gears, or 3.9 gears and buy an ARB air locker for a Prado front. Is that correct ?

Yes I agree with you. My table must be wrong for the Manual. I must have missed changing one formula.
Yes, the ARB front locker part number is listed in the first post and there is also a link to the ARB catalog. It lists the same part numbers for both the Prado 120 (8" gears") and the Hilux. You need the ARB RD111 for the front fr the 3.909 and 4.1 diff.
Try ringing Dennis Smith at http://www.hiluxwreckers.com.au He has not got one but he said he found a couple that were too far away for me (so might be close to you). Tell him you have been talking to Rod Webster. You now have the photos to ID the diff before you buy in my other sticky thread.
