Most people just swap out to a SMF, so you probably won't get much info.
After reading the LuK RepSet catalog, I think you got the right part... for a 12" upgrade.
I'm guessing perhaps there's an upgraded 12" DMF flywheel floating around somewhere?
I'm thinking you have three options here:
1. Have a local machinist add some new bolt holes in the flywheel for the new pressure plate. Any machinist worth his salt ought to be able to do this easily.
2. Send your kit back and get the 11" DMF kit(07-076)
3. Send your kit back and get the 12" SMF kit.
