Interesting, I had the same idea, of adding pins to my FEL forks so I could use them on my 3pt lift too. I have a set for my JD419 FEL. I'll post pics when I get a chance to take some. The advantage of the forks on the 3pt is that it keeps the load more level than forks on the FEL. As you lift the fel, the forks tip back. Conversely, if you carry a lifted load level, it tips forward when you lower it. Probably obvious to most folks, but I hadn't thought about it till the first time I carried a load with the FEL forks. Of course the 3pt can't lift very high or reach into a truck very far.
