M923A2 VIN question

I think only the rebuilt trucks have it stamped there

I am also looking. I currently have two M923A2 BMY. One is a reset with the 1/2 numbers stamped about center of axle on left side of the frame. The non reset are un found so far.

I have searched far and wide on one of my non rebuilt trucks and the only place it had serial numbers is on the data plate and it has a black barcode serial tag next to the data plate. Unless there is some secret spot that has it marked on the frame that I can't find, the passenger dash area plates are the only serial markings on it.

I never found anything on the frame rails. Stripped both of them

My non-rebuilt/non-reset BMY 923A2 has no serial numbers on the frame that I can find. Only serial numbers found are the two data plates on the passenger side dash.

Here is an interesting one. I go to get SF-97 form from GL and I give them the number I find on the frame right behind the steering box. They say that is the MSN and to keep looking. I have an MSN number for it and it is different. I might have to contact the titling department directly with all of the numbers I find and ask them which one I should use. Fun times titling a new 5 ton.

I just Got a Truck from GP 931A2 have the VIN 31-03741.How do you find the year?

The vertical numbers are part number
The VIN Number might be hidden under multiple layers of paint. Keep searching and you will find it. you may have to remove a few layers of paint to find it
