My friend and I put a stage II in his n/a 1986 toyota supra. I always hated that car, and I always hated driving that car even more. After I helped him put the stage II in, (and to this day I still have no idea why he wanted it so badly) the thing is a bastard to drive. It is nothing special and its a DD, but driving it in traffic is the absolute worst cause the clutch is literally on/off. I would totally be able to live with that if the car were something special and or fast, but it is neither. And neither is your truck. Stick with the stock replacement, it will hold plenty. And besides, a stage II with no give will only lessen the service life of your whole drivetrain.
