'83 ur-q Lightened Flywheel Parts?

["Mike Hopton" <MARKDOM.MARKPO.Mike@genesis-microchip.on.ca>]

I'm assembling the parts to replace a standard '83 ur-q
flywheel and clutch assembly with one from an '89-'91
200q (10v). The following are the list of part numbers
that I think I'll need, am I missing any? For instance do 
I need the pilot bearing from an '89-'91 200q?

Any BTDT's most appreciated!

Flywheel    034 105 271 F       
Pressure Plate 035 141 118   
Clutch Disc  035 141 033 H      
Release Fork  016 141 719 A
Release Bearing 01E 141 165 A
Plastic Bumper  01B 141 751   (between release fork and bell housing)
Guide, Release Bearing 016 141 181  (metal)

I may also need a metal spring which holds the
release fork against the plastic bumper, can
anyone confirm this and/or provide a part
number?

Thanks and regards, Mike
