Hey, OP! I forgot to tell you I actually went and got one of these myself. Your PM swayed me. (Thanks, by the way!)
Now I'm even more nervous about doing it after seeing your post. But I would personally just leave it. I agree with a previous post - the factory wasn't perfect, and it's the part of the machine that faces the wall. The next time you see it, you'll be selling it to somebody.
And none of us are HEP, so no worries.
