there are plenty of ways to get this done . some are better. just to answer "your request" why it won't go together ? the clucth disc is not properly aligned . it is just that simple. i use an 0ld main input shaft to align mine. i learned the " hard way " to lift upwards slightly -before- tightening the pressure plate bolts. if it is aligned , it will fall in ... if you install it out of the car , you still will have to align it !! hope this helps .
