As Ethal mentioned, it will fit in with the ADO16 Front Engine Plate as is.
I usually trim them back on the band saw then clean up that edge on the linisher.
Or you could swap with the parts from the 998, however, if you want to use the late cover and tensioner,there is one hole for the cover that you won't get a bolt in to as it lands 1/2 on the block and 1/2 over fresh air. With these, I countersink them from the back and fit a 5/16" UNF Countersunk Bolt in from the engine side, but just remember to fit that screw in before fitting up the plate to the engine. You'll find you wont need to put a tool to it when tightening, as it'll self lock when doing the nut up, or at least, they have for me !. Also, be aware that the included angle for most UNF Countersunk Screws is 80 degrees and not the more common 90.
