It may be best just to go to the source here
http://www.toyota.com/tacoma/specs.html I usually don't trust a lot of those "indie" sights much anymore, I've been led into to many mistakes in the past, even from info I've gotten here (nobody is perfect), so I always verify with the manufacture before I pull the trigger on anything.
Interestingly enough it shows that 358's are available with the 4 cyl 4x4 as you said, but only for the auto and yours is manual............curious.
But the bottom line is if you're going to drop in a trd rear end in, it's going to have 373's. So you will have to change your front to match.
