I don't know if all of the T-hawk drivens were the same, but some of them required mouting the drive clutch backwards on the engine shaft to match the driven's centerline. It's a stock setup, so it shouldn't require any spacing mods, but just an FYI in case you hadn't seen them installed before.
With the drive clutch installed backwards, you have to push forward for reverse and turn left for right, but you get used to it pretty quickly.
