HELP! Need 2nd gen.MC Flywheel and clutch upgrade opinion!

[Triston Harlington <quattro@u.washington.edu>]

 I am asking for opinions, BTBT's on type44 clutch upgrades!

  I need some questions answered as well.
      1.) Are all the clutch disks and pressure plates interchangeable
         between early-late MC and 91'200 3b motors????
    
      2.)Are the Flywheels diferent between the late MC and the 91'200?

      3.)Can I lighten my early MC flywheel to the level of the later
         MC flywheel (inexpensively and reliably)

      4.) Does any one actually know what these (3) flywheels weigh??

      5.) What are the risks and benefits of running a alum. flywheel
          
      6.)   where can I get one? 
         
      7.)   How much do they cost???


 I would be very appreciative to any one who could answer any of these
 
 questions for me!

 Thanks--- Triston Harlington- Seattle
