 Just curious how far apart the cast date is/could be from the stamped date on the tube??
  (This is a 10-bolt rear from a 1968 Camaro, ... 3.08:1 posi )
  If I'm reading the cast date clearly, ...I believe it's " F 26 7 ", ...where the stamped date is " PE 0918 G1 ". 
   
    If I'm correct, ...that's June 26th '67 cast vs. Sept. 18th stamped. That's about a 2  1/2 month spread which seems like a lot to me, ...but maybe it's 'typical'?
 
     Related, ...these are the numbers off the ring gear: " 1 GM 3790629 12 37 9 67 ", ...which (9 67) seems to match the stamped date.
 
    
   Thanks in advance for any info,
 
    Kevin

end of model years always has an effect on when parts are cast vs assembled.

    ...true. But this is an early model year build '68,  with Sept/Oct '67 dated parts. I suppose the axle housing itself was 'left over' from '67, ...and not used until later in the year.
