Which clutch for my Rover v8

[timnutt]

Hi,

I need a new clutch for my kit car, but I don't know which one to buy. I have a Rover v8 3.9 litre engine. It was originally from a Land Rover Discovery. I had to change the flywheel to one from an Rover SD1 (came with clutch) as the Land Rover one wouldn't fit inside the LT77 gearbox bellhousing. I assume then I need an SD1 clutch kit like this one:

Does anyone have any experience of this and know whether I'm looking at the right one.
Thanks!
