They will work, you just have to make sure the spline count on the transfer case is the same. Count the splines on the output shaft of the trans it's either going to be a 22 or a 23 spline, you need the matching transfer case for either spline count.
Diego, GVR4s and 5spd DSMs share the same final drive ratio, it's the automatics, Galant GSX, and I believe the RS as well, have the different final drive ratio on the rear differential.
