i am not positive on this, but i think - remember hearing that the 78 round headlight had the narrow frame, and the 78 square headlight had the wide frame. i know the 78 shortbed square light we built a few years ago had the wide frame, we used a 79 bed on it.

The connection I have been finding is if the truck has a factory rear tank or not. No tank seems to be narrow. With tank seems to be wide. Maybe this is when I learn otherwise though.
I believe that the widening part of the frame takes place just a little before the rear of a standard cab.

All crewcabs up to 771/2 2 and 4wd had the narrow frame also highboys. 2wds reg. cabs had the wide frame in starting in 73. Im not sure about the supercabs but I think they were wide frame 2wd in 73 and went wide frame 4x4 in 771/2.

where the front frames the same width from 73-79 on a f-250 4x4??
Question is we want to mount a snow plow on a 78 f-250 4x4
and the say the frame mounts for the plow are different from a 73-77 then
another one for 78-79...WHY?

Ford used the old late 60 style frame up to 77 1/2 in their 3/4 ton 4x4s and crewcabs why I dont know. This means the front of the frame is diffrent also.
This frame was the same width front to back. The newer frame was the same width as the older frame in the front and was wider in the rear but even though the frames were the same width in the front nothing else was the same.

the width of the front of the frames is the same the differance btw the highboy frame to the 77 1/2 to 79 front frame is the spring mounts and frame ends the early one needed extra brackets to mount the bumper the later ones didn't as for why ford didn't update the frames till 77.5 Ithink ford considered the 3/4 ton work/contractor rigs not play toys thats probabley why the option list is so small on these trucks
