the mounting tab for the vent is hanging by a thread. Still in place but bends back and forth instead of letting the hinges work. I figure it will break about any time. I've got the door(vent) off and want to weld the tab in place. I need to know about what angle the tab in in relation to the cab. Right now it is about parrellel to the door, doesn't look right. should it be 90 degrees or somewhere in between. Oh, this is on a '48 1/2 ton. Chev., of course.
