I'm also in the middle of a swap. I'm putting 87 4runner parts into my 84 xcab.I'd advise getting a complete donor truck. There are differences on some 22R's that are supposed to make it difficult to bolt up 22RE manifolds. I'm installing a rebuilt 22RE block & the EFI parts off the 87, so I'm not up on the differences.

Take lots pictures of the disassembly...saves a lot of second guessing as it goes back together (take lots more than you think you'll need, invariably the one part you want to check out is hidden by an otherwise perfect camera angle).

I haven't tackled the wireing yet, looks like it'll be a head scratcher, pretty much just like that article says.

It can be done, but it's no weekend project.
