I have those same type of numbers on my frame. 1967 2wd frame, and the last part ends in -99. Definately not a '99 frame! I'll get the exact numbers later. Must be a part # or plan #.

These are on my driver's side framerail, just behind the forward cab mount. I'm very sure that 2-23-99 is not the date, since the frame is a 1967. Might be a line code, and maybe the other is a part number. My best guess anyway.

Genarally, a 7 digit part number that starts with 38 would be around 67-68 vintage, and a 7 digit number that starts with 39 would be 69-72 vintage. Not sure if that holds true on frames however...
I think duncan and son are up on these...

franky69c10 · 01-22-2011, 07:58 PM

More numbers anyone? Is there a site where I can look up these # so I can see what's the info on the frame

On that one, 7 is the last digit of the year, (1967), S is the manufacturing plant, and the last 6 are the vin serial number, the same as the last 6 of the title, or if the original cab is in place.
