That would be correct. I think that may be a date code ie: 11th month, 13th day but I don't know for sure.

Dave ;

Never fear any flaming here ! .

The good folks here collectively know _everything_ and are always willing to share , no question is foolish no matter how mundane you think it is .

O.K. ? .

Seriously , i worked on these trucks when new , later i was a Dealer Mechanic and I have learned more here than all those years of hands on working so ASK AWAY ! .
