Hey,

I am trying to find out what some numbers are stamped on the frame of my truck. It is a 1959 Ford F-250 4X4, Manual, Standard cab, Fleetside

The first one is stamped on drivers side frame, Visible from the outside except it is upside down and appears to read -

CB9TT-AK

The second number is stamped on the top of the frame visible when looking under the hood and appears to read -

4 25 8YK61642


Any help understanding what these numbers may be would be very appreciated.

Cheers
