4000 SU Serial Number??

[Lynn Patrick]

Finally scratched off to see the serial number, & now I'm confused! Stamped on the "flat spot" is 9L26B on top w/AF7023 underneath. I can't find (yet) any mention of such a number. Would someone translate it for me?
Thanks!!

While waiting for Sean or Destroked to reply look at this thread, there are two photos of numbers and you took the ones from the wrong side.

Trying to figure out what i have, was told Ford 4000. I have enclosed a couple pictures. Wondering if it a 3000 grill or 4000 grill. From what I have read the SU used some 3000 parts.

The thread also tells where to look for the model number in a somewhat non-standard place.

Thanks Andy. I'll check the other side tomorrow!

9L26B is the date code for when the transmission was assembled, which was November 16, 1969. AF7023 is an assembly code for the transmission, which only means something to the Ford Engineers.
