Chassis VIN stamping P.I. work...

 

On C1 frames, VIN #'s were stamped on the drivers side, just across from the "X" frame

57 Chassis' were built/stamped at the A.O. Smith plant in Wisconsin

Rubber "pads" were placed in several locations, before the body was placed on the frame.

The VIN# should be in the approx. location of this pad.

Nothing there??

Starting to show up...

There it is!  And it matches the VIN.  ; )
