BroncoBill, that brochure is interesting because I have an early build date 78 with push bar and lights, and the lights are mounted below the horizontal bar. The picture shows them mounted above the bar.
Just another "Bronco Mystery".....?
Hmm, I'm not sure I'm clear on what you're saying. The factory foglights were usually mounted on *top* of the front bumper & under the hoop of the pushbar. The "bar" that the photo shows them mounted above is in fact the front bumper it's just that the one in the photo is painted flat black instead of chrome as Ford was wont to do in those days (they thought it looked "european" and was therefore cool).
Now, having said that. The assembly lines back in the 70's were a FAR cry from the assembly lines of today. It may be an early build date truck but dig deeper to see WHEN in the week it was built. I remember going to buy a brand new Plymouth with my old man back in 75'76' and he flat out refused to take delivery when we showed up because he scrutinized the build sheet & saw it had been built on a Friday. He wouldn't take anything built later than a Wednesday, figuring the guys on the line were too preoccupied with the upcoming weekend on Thurs & Fri and would be doing a sloppy job. Call him Quirky but he got 170K out of that freaking Mopar & this was back in the day when you'd need a set of rings at 60K. It wouldn't surprise me to learn that the guys on the line sometimes had their own opinion of what looked best & just where those lights should go.
Also, just how certain are you that your truck is still in it's original factory configuration ? 30yrs man, that can be a whole lot of owners doing who knows what with it.
