68 C-10 rear end identification and code

[Scott's 68ChevyC10]

I have most of my identification code exposed through all of the grease and road grime, what does this code mean F38(either a 9 or a 0) 6838?

Thank you for any help

All the diff charts I have show two letters followed by a string of numbers.

Where was this number located? The code number for '68 should be two letters in a series of letters and numbers on the axle tube or the rear housing web. Here is a link to the charts I posted a few years ago.

And a couple of pictures of code locations on the axles. Third picture with the code on the side of the third member was posted by member "swamp rat".

I think I attached the picture of the reared housing showing the code or at least what I can decipher of it.

That is the casting number not the code #. The code # would be stamped into the metal like the pictures I posted.

Yeah I cannot see those. I NEED to get it cleaned much better. Thank you for the help thus far.
