Ordered and received these, but they included washers in the package. Not sure if I'm to use the washers or not? I emailed them 2 days ago, no response yet. Called a while ago, had to leave a message. Such a simple issue, but their instructions don't mention using washers and their pictures both on the package they sent and online don't show washers. Whats the deal? Are the washers perhaps for only bikes that had them? My KTM had none, but it didn't have that style of locking nut either. I haven't wanted to tighten them up until I know for sure. Thanks.
