They stopped putting 22R's in 4wd trucks and Runners in '88. However, 2wd models still got 'em. I really don't know the cutoff date but a friend of mine had a '90 2wd truck w/ a 22R.

 

It's a 2 wheel drive pickup. I didn't really want it but i was looking for an extended cab yota pickup for cheap. I really wanted the 22re but for $ 600 I cant complain. I'm not sure of the cut off date either for the trucks but i think you could still special order them up to 92? Another odd thing is my 87 4runner yota manual has the repair section for the solid front axle in it? Whats up with that?
