NEW boxed Flywheel complete with its Ring gear to fit :-
Vauxhall Victor FD / FE
Vauxhall Viva OHC  Magnum Firenza  Viva GT
 
This flywheel has many different clutch mounting holes  (universal)  to enable use with different sizes of clutches. 
So it can be used on all of the saloon car Slant 4 engine sizes & their clutches.   

So it is suitable for the 1600cc/  1800cc  small clutches. 

And most importantly for the 8.5" clutches,  on  the Viva GT / Victor 2000cc  and also the 2300cc  Magnum/Firenza/Victor. 

Important note: This Flywheel is NOT suitable for the Bedford CF van with the 9 1/4" clutch.   

This is an ex MOD  army flywheel, -  hence the multi-use of applications.    It is MOD boxed & wrapped, so is in very good condition. 
It is standard specification,   so NOT a lightened / balanced flywheel.
