I believe the 4.77 12 bolt ring and pinions are still available from dealers, as thats where I purchased mine. (or at least one of my sets)

All second gen 4x4 Amigo's with the 2 liter engine had 4.77 gears. The rears were Dana 44, so that is out. The fronts axles were all ten bolt, BUT there was only a six month period when they used the Corporate ten bolt. (Wich is what you need.) The rest were Dana 10 bolts which are slightly different.

I don't remember off the top of my head which six month period that was, but I'm sure I posted it here before. I found all the information I needed online, so I'm sure you can too. I'll look through my stuff again to try to find it for you. You might try PlanetIsuzu.com too. They have a wealth of information onAmigo's and troopers, as does the International trooper Owners Guild.

Anyway, take this ifo you have, go to Car-part.com type in what you are looking for and you'll start to see just how freaking easy it is going to be to come across these things. Some have the vin numbers listed. Some you'll have to call about. Don't think that they will take one apart to look at the gear make for you. Know what you are looking for. VIN ID might be possible too.


From another angle, There's a decent chance the OAL of the Dana axle housing is the same and would bolt right up. that would require some other manuals, and/or scrounging around a junk yard though.
