Goodmorning! So I bounced around on my Sled today and when I was washing the mud off I noticed a large machined hole in my swing arm just in front of the rear tyre. I don't remember seeing it like this before but I cannot for the life of me remember what it looked like. I presume there is some sort of cover which has fallen off. Would some kind sledder out there post the same picture with whatever is meant to be there in place so I can order a replacement. Thanks!
