Is there any type of date coding on 8.75 rear differential center sections? 741 case if that makes a difference.Thanks

I believe the assemble date is stamped in white paint on the drivers side of the pinion snout and I think the casting has a date cast into it but I cant swear to that, I will try to look at one later if no one confirms it.

Careful, your character's showing!

Probally not considering how many where made and used and how long they made them

Last one. Though not a 741 as in your case but, yes, there are several date references on some. It appears that the gears in this instance were forged 6 days prior to installation in the case or at least in assembly / accountability process.

Close up view showing it actually is white paint, even though it looks yellow at first glance.
