2012ish the updated the drum to a longer drum to accommodate 4 full wraps with a 3/4" rope. Also, note sure the time period, but the mounting plate has changed for the better in my opinion. Originally there was one pigtail and additional fairleads. These fairleads were being misused, and there were failures. They now have only top fairleads, and both right and left pigtails. Much better now.
