DUAL MASS FLYWHEEL CONVERSION TD5's

I am currently converting my Defender TD5 to a single mass flywheel as my gear box has Shatt itself & this should not happen to a gearbox on the NEW dual mass system. I have had the Flywheel machined to a single mass & looking for the correct 267mm clutch friction plate possibly out of a 3.9I V8 Disco LT77. I know the 300 TDI clutch fits onto the TD5 gear box but i am unsure if the LT77 V8 Disco clutch will fit so if any one out there knows please let me know. Thanks & if any one else has TD5 Dual Mass problems let me know.
