Well, not being able to get into gear is probably a result of the input shaft rotating along with the engine at idle as opposed to NOT rotating so that you can actually get the shifter into gear. 2 possibilities I can think of.
1. the pilot bearing is damaged and binds up against the input shaft. If it's stuck there, it'll keep the input shaft spinning along with the flywheel at idle and your blockers won't stand a chance of stopping the input shaft from spinning.
2. the new clutch isn't disengaging enough and is thereby holding the input shaft to the flywheel. again, this would cause the input shaft to keep spinning along with the motor at idle. Again, this will just burn up your blockers trying to stop the rotational motion of the input shaft.
maybe the old clutch was worn out and very thin. also, the new clutch is probably thicker. (think of putting on new brake pads). Now, the clutch could need a proper bleeding. If that's the case, what was enough range of motion with the old clutch is now NOT enough range of motion with the new clutch. So, whereas the old clutch would disengage enough given the limited range of motion, the new clutch is too fat and the limited range of motion is just too... limited.
3. You should have purchased the SPEC clutch! just kidding. I like the way that kevlar grabs though.
so... you pulled the entire motor to change the clutch?
