it's not going to bolt in. sorry.
the R/Ts are 2wd only. you just said yours is a 4x4. you're going to have to do an axle flip kit to it in order to make the rear fit, because 2wd Dakota's are spring under axle, the 4x4s are spring over axle.
the R/T rears are all 3.92 ratio with an LSD in the 9.25" axle. that's the only difference that pertains to R/Ts otherwise the 5.9L motor and trans are exactly the same as any other 5.9L of the same year. sucks doesn't it! sorry man, nothing special about the R/T drivetrain other than the gearset, and the 5.9L motor. and you can option up to the gearset in any of the trucks if you wanted to.
now, if you just want the motor, it will drop right into place where your 5.2L sits, and probably don't even need an R/T PCM or the MP one unless your 5.9 has other mods to it like headers, intake, etc.
the 5.9Ls respond well to the "simple" bolt ons while it's out of the truck--intake manifold, headers, camshaft, computer tune, shift kit in the auto trans, etc. you should be able to make 350-380 hp if you pick the right cam and work with the right aftermarket engine tuner like Sean at SCT
