Got the L-39 and grapple back today. What the dealer did was rebuild the top "pocket" making it deeper. Hopefully it does the job. Just in case anyone is interested the dealer didn't charge me for the modifications (which makes sense) or transport since they did the 50 hour at the same time and my salesperson and I had agreed that everything, including transport, would be included in the original price. They are also moving my other tractor from one property to the other at no charge (about 20 miles). Hard to complain about any of this.
