We've done the bumpers as one piece like this for the past few seasons, but you could do them as halves, also. I'm not sure it would work well if you wanted each side to have its own bumper.

One thing to watch out for with these is that, the first time we did this, we made our hooks too weak, such that they gradually got bent up over time by the force from the draw latches and the draw latches stopped latching.
