The H25A (circa 2001) I replaced the H20A (April 1995) with came with a manual gearbox that has a different rear spline size, this was the limiting factor in using the newer box since it didn't have the newer front and rear driveshafts with the newer motor and gearbox. Some time down the track however, I'll probably replace the older, weaker box with the newer...

I just want to know if all I'll need is the driveshafts from a 2001 model, or if they updated the diffs and driveshaft couplers too?
