Chassis numbers
I was cleaning up my frame under the cab so I could put in the trailing arm crossmember, replace the body mounts etc. when I came across a set of numbers. They are on the outside of the frame, passanger side, just behind the front cab mount. They are as shown:
3999918-73OX 7 - 10 - 12 Does any one know what they means, Thanks (I will try to get a pic) |
