You shouldn't have any problems if you cut the seatbelt positioner. It doesn't weaken it at all. Some people have hammered it so it would fit around the brackets if your more comfortable with that. It was pretty easy to cut it though. I just used a marker to mark what I needed to cut out, clamped it to a saw hoarse, and cut it with a jigsaw that had a metal cutting blade on it. Make sure the piece is clamped down though. I tried cutting it first by just holding it down and the blade skipped of and nicked my hand pretty good.
