Very nice looking job. Real similiar to how they are on my Kubota B3030. The only real difference is that on the Kubota links there is a slot in the outer tube that allows a couple of inches of sway. That is handy sometimes when you don't want the 3PT implement to be totally rigid. As far as the pins that go in the holes to regulate the width, I don't use the hairpins to hold them in anymore. It gets to be a pain to mess with them everytime you need to hook up to an implement. I havn't lost a pin yet, either. I think it would take a huge bump to make them pop out of the holes, especially if they are an inch or so longer than necessary. Good luck.
