I just picked up a used ULE body. It does not appear to have the c-clip and washer. Is there a way to confirm this? I have not used it yet so I'm not sure if body is mushroomed, it does not appear to be. I have an extra c-clip and washer and it went in with no issue. Is it recessed for only one I assume? I just want to make sure so I don't create more issues. Thanks in advance.
