A727 Torque Converter ID numbers

[AR67GTX]

Finally found some small, stamped numbers on this old worn 11 in converter in my 67 GTX but I haven't had much luck finding any reference material to make sense of them.

The first three are 936 but there's a 4th one that could be a 3 or a B - it's pretty buggered up. So, it's either 9363 or 936B. Has anyone seen a guide to such numbers?

Build date?? was surfing the web today and saw a website for a hi-perf trans shop in Canton,Oh. that owner's dad previously had. Used to make/sell 'Banana coverters'. I used one of their 4500 stall ones years ago. May have to make a roadtrip to "share" the memories.
