It appears there is a differance between a 40 and 41 pickup as to how the center windshield post is attached. If someone has a 40 can you tell me if the inside center post attaches only to the inner whindshield frame or is there a bolt of some sort that goes through both pieces and into the for lack of a better word the header above the windshield. When I got my 40 that upper panel was rusted through so I don't know, I am ready to put the windshield in but would like to know if I have to drill and put a captive nut above the windshield, Thanks
