I've never been one to buck the easy button if it gets me where I need to go with the least amount of fuss - provided it's not outright hackery. I like the simplicity of the bracket though.
Notching the bellhousing is easy, but my car is an ex-318 with its original 904 at the back. As such, my converter is still neutrally balanced; I used a B&M flexplate to get the roller LA360 to play nice. It's going to take another converter or I'll have to weld on some weights to the existing one.
