Looking for any documentation '69 Barracuda Fastback

Is the casting date the smaller numbers below the 2077041 and in front of the 26? There are some smaller numbers there, but can't tell if it just says 222 or if there is a number in front and/or behind the 222? It's hard to tell, even getting up close and blowing up the pics if they are numbers. The 222 is easy to see, but in front and behind it looks like just raised metal, hard to tell if they are numbers or not.

Thanks again,
Dan

Here is something else that may apply. found it on Mymopar.com

Any 8-3/4" center section may be interchanged for another as an entire assembly, with the exception of center sections manufactured prior to model year 1964 (See Section 1: "Thrust Block Variations").
