Frame VIN not enough digits
I found this on the right side of the frame below the firewall. It says the frame is from a 1976 F150 4X4 but the engine code position is all wrong. Also, the frame is 37.5 inches wide like the 80-86 models. Has anyone ever seen the wrong #'s stamped into the frame? Are there any other locations on the frame that may have the VIN stamped into it?
There is also no fabrication work done to the frame.
Been following this in the 1973-1979 forum.
Could that be a 1980 Vin number, and some of the lettering has been rubbed off, not stamped on it proper? 1980 vin numbers were also 11 digit. 1981 was the first year of the 17 digit.
Are there a lot of holes along the frame rails? I mean a bunch of them? Supposedly strength holes. Affectionately called the "Swiss Cheese Frame" by fellow Ford nuts.
That would place the frame as a 1980.
There should be a tag on the cowl or firewall, just below the hood weatherstrip.
The obvious one in the cab.
And the one on the frame.
The big holes are about half way along the frame in the "center" so to speak. You would notice them if you saw them.
How is the front bumper held on? It should be bolted right to the frame rails. If it isn't or held on with brackets that suggests a earlier frame.
Usually the cab has to be removed to see it.
I'm trying to find the 1980 Vin #'s right now.
Even if the frame is an 1980 that still doesn't explain suspension parts from 2 /3 years later
I see by your VIN it's a 1980 F150 4x4, assembled in Michigan, but I can't find an engine code of "c".
All I see in my book is the following engine codes:
E: 4.9L (300-6cyl)
F: 5.0L (302 v/8)
W: 5.8L (351M v/8)
Z: 6.6L (400 v/8)
Maybe my book is missing some codes.

Where do you see that in the VIN# ?
F14CLA45931
I see it as a september built 1976 model.

I'll have to rap him in the side of the head.
Some parts guy is/was.
Too bad there isn't a chart for Ford truck VIN's, all years.

Yours looks like it's parts of a 17 character VIN to me.
F14= F150 reg cab 4x4
C = 1982 model year
L = Michigan Truck plant
A4539 = Sequence number
Makes sense to me that the framerail wouldn't get stamped with the engine, because it's the same no matter which engine is installed on a F150.
I'll check the frame VIN on my 81 F100 chassis, I'll bet it's a similar looking deal.

The Year code letter on my 1981 is a "B" so what you are saying does make some sence. Although I've never heard of partial VIN's on frames before.
Interesting.

The number on the framerail on an 80-86 truck is usually not a complete VIN, and, on a one of mine is a Ford part #, not even related in any way to the VIN.
Yours looks like it's parts of a 17 character VIN to me.

Sorry but the 17 digit codes don't look anything like this except for the very last part
I tried every way possible to figure out of that it may be a partial.
Without any success.
The coding for the 81 & newer had segments of the Vin that meant something.
Here's what I mean

If you count 11 didgits backwards it doesn't make any sense.
We need someone here with a "1980" Truck to verify the Vin#
I punched up this number F14CLGA5931 in a VIN# decoder and it came up a 1980 ...but I don't trust the source .
remember folks that the last of 79's consecutive built numbers ended with FK????

If that 4 is actually a letter,like the letter H that makes the frame a 78.
