You will probably find that you already have a 2.8 flywheel.
See here Flywheel thread clicky.

I used a clutch kit for 2.8 capri with no problems.

Hi,
I have a 2.9 clutch on a 2.8 flywheel on a 2.9 engine. No problems.

How does a 2.9 clutch vary from a 2.8, larger diameter ?

IIRC, There was an issue resolved by Adrian Venn ( adrian@ ) where an occasional permutation of 2.8 clutch/ 2.9 flywheel or vice versa caused a problem of premature clutch slip, unable to engage clutch fully to select a gear, this can be remediied by machining a small amount off the inner part of the flywheel to extend the swept area of the face of the flywheel. Or something like that.

Can't find it, but it was on here s couple of years ago.

Here is the thread - although this may be more to do with certain types of clutch matching with existing 2.9 flywheel?

Note that the generic 2.9 granada clutch kits that are in the market place have problems when fitted to the TVR flywheel and after a few thousand miles the centre rivets clash and the clutch again starts to slip at high load points (ensure that the people and or yourself check for this) as I have machined some 30 odd flywheels in the past to suit. Adrian@
After 8 Private mails, on why this is so...the OE plate on this car is an AP version and this is matched to a flywheel where the driven plate area (the face that the plate runs on) has an I.D. that where it drops down to the bolt facing area is 2MM TOO SMALL and requires a relief machining from the flywheel to allow the plate rivets to drop into as the friction material wears away....OR the engine side of the plate runs on the rivets and the clutch slips.
