If you're interested in solving the problem instead of complaining about the parts supplier, contact me by PM. There is a quick, easy fix for it. I can either make the necessary modifications to the end cap on your new part, or tell you how to do it.

Sorry Jerry I was not complaining about the parts supplier, more so curious if the manufacturer inadvertently installed the wrong end cap. Which unless brought to thier attention, the supplier may never know. Also others may or may not have the same issue if they buy a new MC from any parts supplier. I was only making a statement. If you read my post to the end you would see I am happy with the parts supplier & was only stating my experience. I appreciate your offer but I already fixed the issue by installing my old end cap on the MC.
