the front third member will fit into the front and rear housing of a samauri, but, only the front(so you have to find 2 fronts)and you have to tear the one you put into the rear apart and put the samuri side gears in to the kick third. i beleive the spline count is different. there are also 2 different gear ratios (actually more , but these two are the most common)4.63 to 1 , and 5.12 to 1 . the 5.12s are in stickshifts and the 4.63s are in automatics. there are other ratios like 4.88 and 5.89 but they were only produced for special years and i'm not sure on years.
hope that helps
