I don't want to go that far as changing doors, actually my doors don't have the vent. The latches don't work fine, that's why I want to change them. I have to drive with the window down and my arm outside in order to avoid the door to open. My choice was actually repo. Now you've got me thinking. I wanted to put the 47-51 latches, since the cab is 49, but don't know if they will work if the door has now 52-55, besides, 47-51 are more expensive. Handles are already changed to 52-55.
Thanks
