I would think so as it is an SS part.  As I mentioned, I have the actual grille emblem with the same six-digit number, which seems to pre-date? the standard seven-digit number.

Well I was finally able to do some checking on the underhood temps.  I drove the Z for between 2-3 miles to get the engine up to temp.  The outside air temp was in the mid 80's.  While driving the temp gauge stayed right around the first quarter marking, maybe one mark up toward the half marking.  While idling in my driveway the gauge read right at the one half marking.  The engine would not hold a steady idle but slowly had the idle decrease until the engine died.  This happened 3-4 times.  While the engine was not running the temp gauge would increase until it was between the one half marking and the three quarter marking.  This I take to be normal due to heat soak. 
Here are the temps I recorded with an infrared gun: 

radiator hose at thermostat- 183, bottom radiator hose- 164
exhaust manifold left hand side (driver's) from front to back- 364, 455, 417
exhaust manifold right hand (passenger) side again from front to back- 433, 570, 562
intake manifold at the high rise part on driver's side- 227
radiator across top- 145
radiator across bottom- 99
valve cover driver's side- 164
valve cover passenger side- 194
driver's side head-194, right at the temp sensor was 179
passenger side head- 253

I wasn't able to get accurate readings anywhere else or didn't think of trying anywhere else.  Definitely the right hand side (passenger) of the engine is a lot hotter than the driver's side.  I wasn't able to check other things while taking these temp readings as the engine was too hot to touch.  Any ideas out there?  Thanks again guys for all your help and opinions.  Just to add a side note:  the engine used to be able to idle for extended periods right at 900-1,000 rpm, with the temp gauge reading not much higher than the one quarter marking and without dying.  It also would restart while warm or hot with no problem.

So what which car would have made it out the door first? Does your earlier trim tag indicate your car just left the fisher plant before his, but once it was at GM, his got done first? What is the build week of his car vs. yours?

The 1969 body number was assigned when the plant accepted the order for production, not when the body was built, so there could be a relatively short time span or a much longer span, depending on material availability, sales priorities, etc. Once the Fisher body was received at the Chevrolet Body Bank and the VIN was assigned, it would be unusual for the body release to the Chevrolet assembly system to be delayed more than a few hours.


So was there planning coordination between Fisher and Chevrolet so that Fisher did not release orders to the system which might have material availability issues on the Chevrolet side? There must have been, or some type of central planning?

Very hard to change a ONE into a ZERO.
easiest number to hide of any of them 1111481 is a common number too
look at the 1's theres no top or bottom to it a 0 covers most/all of it I actually blew that pic above WAY way up and something isnt right

The Dynacorn stuff I have seen also needs a bunch of metal work to make the fit right also so you might as well fix your orig. body and recover and extra cost when it comes time to sell. You will always get more for a real GM body versus a Dynacorn.
