I bought a QH from Rural King for my 3320 and love it but I see that the pins fit loosely in the openings. I also see KBOH sells bushings. My question is do you buy a set for each attachment which in my case will be $120 of bushings? Is there a way to fill the gap in the QH instead? Are there any other options out there instead of $30 sets of bushings per implement. Such as steel pipe or ? I can fit a pin in to the hole on the pin when it is hooked up to the QH.
