I'm hoping y'all can tell me what the holes are in this pic. There was nothing attached when I bought the truck. As you can see I've installed a roll bar and the holes are just forward of the front part of the bar in the back of the door jam (B pillar) facing rearward. The top 2 holes are threaded. Maybe 5/16". Always appreciative of your help!!!
Thanks and Merry XMAS
John

My guess would be, mount holes for the bulk head used in early ranch hand U15 and half cab U14 models.

'72 was the last original U14 which had a bulkhead. My '72 U14 Sport has bucket seats and a bulkhead.

71' was the last year of the bench seat and also the bulk head.

'71 was the last year of the front bench seat, but you could get a half cab (which automatically came with a bulk head) throughout the 1972 model year. The holes would have been omitted in 1973, which makes adding a half cab to any '73-'77 Bronco an enormous pain...

This is true, had bench seat on the brain I guess, I've got a boat load of 72' u14 statistics lol.

My 73 Sport built in October 72 had them. I have three 73 broncos that don't have them which were built in 73.
