Odd rear code on '69 Z/28

[nuch_ss396]

Can a 04C body have a 05/15 rear installed from the factory?Could the car have been sidelined due to an unavaliable 3:31 axel?Can someone tell me from the VIN when it(the VIN)was issued?

Steve,

Your VIN places production in or around the 3rd week of April '69.  As has been discussed previously here, production would be +/- one week from that.
04/69 Norwood VINs were in the 628000 to 635000 range ( close approximation ).

Well,

It's starting to look like maybe this rear may not be original to the car.

Indications I'm getting from members here is that one month is too long
to sideline a car - for a rear.

So, that leaves me with this question:  If a rear failed under warranty,
would a complete rear be ordered, or just the components to rebuild it?

Jerry, did you ever hear of an original rear housing failing that early in the
cars life ( one month )?  I've seen where an axle tube broke under hard
acceleration, but this was a COPO car.  Did/do the Z/28's have that kind
of torque? 

I'm just trying to explain the existence of this rear in the car at this point in time.

It's probably not.Even though the 3 previous owners say it is.With the evidence of some drag race history who would use a 3:31 for that purpose?Unless they swapped gears in the BS housing,it does have the welded tubes.I've checked for a build sheet under the seats with no luck.What other locations should I look?

Also,whats the deal with the X3 mark behind the rear seat back?

The X3 was to signify an X33 car.
