You definetly need to get bigger balls! Not for you but on your joints. Guys these are strong hard quality plastic here. In fact maybe to strong. The pin holes were a bitch. If my pins were not knareld they most certainly are now trying to slide them thru using plyer but I dont dare say pre drill in fear of loosening to much. I recommend some brand new smooth pins with a a beveled tip on one end. Although this plastic is so tough knarled pins or not this plastic might wear and cut thru your metal pins.
Buy the way two new joints do fit but barely. A little sanding and they fit better.
