Anybody got any suggestions as what to plug the holes with on a tour pak where the speakers and back rest are when removed? The speaker holes are big at 9/16 inch and there are six of them. The back rest holes are 3/8 inch. I've tried the hardware store and they didn't have anything that big or that small. A bunch bigger stuff though. And even looking online I any found one place that has something that MIGHT work so I've got that ordered. But you got any suggestions of what I might want to bolt in those locations. I'm thinking maybe some amber reflectors for the speaker holes but I'm drawing a blank on the backrest. So you got any ideas? I ride solo so don't need or want the stuff there. Just gets in my way.
