do I need these skid plate spacers?

Hello all, haven’t stopped in here for a while. Ever since I moved to South FL a few years ago, I haven’t been riding much.

I’ve got Aluminum Products skids. I’ve taken them off plenty of times, but it’s been about 3 years, and I seem to have forgotten how they fit back together. Specifically, the skid plates that go under the foot boards. Each foot board skid plate comes with a few cylinder shaped spacers. However, I’m wondering whether I need them at all? They seem to make the skids seat incorrectly, and they don’t give me enough bolt length to put the washer and nut on.

Any advice? Can I remove them or are they necessary?
