1969 small block timing chain cover #2946797

I have the same part number TC cover that I have kept as a spare and it does have 68 stamped in the little circle to the right, I tried to get a legible picture of it but it is so small it won't show up and the one that's on my 340 right now has the same 68 stamped in the little circle also.
