Loose Quick Attach

My quick attach is loose with all my attachments, but I can't figure out what is worn out. I'd say there is 1/2" to 3/4" (depending on the attachment) of play between the pin and the rectangular hole in the attachment, when engaged. With all the slop I am mangling the pins and the rectangular holes in the attachment. I couldn't even open the quick attach the other night until I did a bunch of filing on the pin (in the dark - fun) because the pins wouldn't retract due to all the dimples...
