I recently picked up a 2004 JD250 Series II and it needs a little love to the door. It currently has only one gas shock, but I plan on adding the second. I'm questioning if there is supposed to be a latch mechanism on the door to hold it in the "up" position or not. When sitting in the machine there is a bracket over the right hand shoulder up in the corner of the cab, and there is also a tab that sticks off the top right corner of the door. What am I missing, or are the two gas shocks enough to hold the door up in position?
