It looks a little like a Hewland differential http://www.wolftronix.com/E10/images/P3260159.jpg
The housing might be special but I bet the gears are front axle from an AWD of that era. Only a few manufacturers of hypoid gears are out there, less than in the '90s. I bet if you took them out you can get the numbers off of them and it might even be gears from a 4WD S10 front axle. That's what I would have used. You need a custom housing because the stock 4WD axles have offset differentials and this one looks like it is on center so it probably wasn't available the way they wanted it. The gears and bearings almost certainly are off the shelf but it's probably hard to find exact lash specs. You'll have to use the bluing contact patch method and make some educated guesses if we can't find the service data. sean On 5/29/19, Tom Hudson via EV <[email protected]> wrote: > Well, I heard back from the mechanic -- he drained the differential oil to > get a look at > it and it was "a metal milkshake".
