...or you could adapt an AW71 automatic OD from a 240. I know a chap that did this and it seems it would be easier than hanging an extra pedal/cylinders,etc. He simply sliced the bell housing(like a big loaf of bread) and rotated it to the B18/20 "upright" position and re-welded it. After a bit of wiring he was out of the slow lane and actually passing other cars! He uses an auxillary trans cooler to avoid messing with the radiator. You might also consider having your rear main seal housing machined to accept the B21 rear main seal if you haven't already. That would eliminate the major source of oil leakage. By the way-I'm intigued by that big chunk of angle iron that appears to be holding up your trans crossmember.
