Well, first, what do you have?

Your pics show a torque converter through what looks suspiciously like the 2.3/2.6 starter hole so I'm guessing it's a 30-80 LE. That is an Aisin-Warner A340H and *not* an Isuzu t-case. Toyota used these for a bazillion years. You sure there's not a bolt on Toy flange for it?
