Which flywheel and clutch

Hi All

I'm in the middle of swapping my 90's tired 2.5 petrol engine for a 300tdi, I'm going to put in a new clutch kit but before I order one I thought i'd check a couple of things.

I'm going to keep the existing gearbox (unless the splines are fooked) so I have already removed the old clutch, flywheel and housing from the back of the tdi and intend to use the petrol housing.

So which flywheel should I be using and what clutch kit??

Cheers for any help

I guess it was a stupid question, removed the petrol engine today and the clutch and flywheel is exactly the same on both vehicles, ah well you live and learn.
