Moser is in Indiana. They custom spline/respline axles all the time; so I don't see them having an issue with this project. Not looking to do this anytime soon... more trying to spur a good discussion. One of the issues with dual Isuzu cases seems to be fluid capacity/cooling of the front case once the output is lopped off. Overall length of the dual Isuzu combo in a 1st gen Amigo leaves the rear driveshaft rather stubby as well <img src="/forums/images/graemlins/lol.gif" alt="" /> I don't know that this combo would be any shorter, though. Another good combo would be the 231's range box/D300 combo mated with the 'box for rocks' kit. What would be REALLY nice is if the Isuzu mainshaft was of a size that it could be machined/resplined to work directly as an input shaft for one of the above combos. <img src="/forums/images/graemlins/cyclops.gif" alt="" />
