93 D16Z to 94 DX D15 Tranny???

I don't know if maybe i need thicker pressure plate or what? I used pressure plate off D15 put it on the D16, maybe i should put D16 pressure plate on, but there the same thickness, and I can't get it to go into gear. Dunno if maybe something to do with hydrualic's tried adjusting my clutch. Maybe buy a new pilot bushing, or maybe its just slave cylinder, can please some one get back to me on it, I'd appreciate it. Thanks
