[QUOTE=aggie91;6608295]vin # is C1545F150363

Breaks down like this:

C = Chassis Type = 2wd
15 = Series = 1/2 ton longbed 127" wheelbase
4 = Truck Type = pickup
5 = Model Year = 1965
F = Assembly Plant = Flint, MI
150363 = Unit Built = This was the 50,363 truck built that year. Each yr starts at 100,001.

The Vin does not specify the rear end ratio on the 65 or 66 model year. There should be numbers/letters stamped on the axle tube near the center section. You might have to clean it off real good to read them.
The code should be something like this: HA02 17W
it breaks down to this:

HA 65-69 3.73
0217 built February 17th
W by Warren Gear

That rear end example is off a rear end that I bought on craigslist. the gears, carrier, and axles had been swapped before I got it, I just wanted to know what year the housing was for my project.

Hope this helps.

Hi Karl,
I found this thread in a Google search and wanted to know the resource used to obtain the decoding of the numbers stamped on the axle as well as the VIN. I currently have 65 C10 and wanted to know the steps to validate your information (specifically to DMV). Is the reference a manual that can be purchased? Thanks for the assist.
