Barn fresh find today, can you help me?

I just picked up a 4-speed transmission today from a guy cleaning his garage out and was told it was early mopar A-Body, small block application. Its been in storage for about 28 years. There was an aluminum tag on it which I believe was the date code ( 4-67 )??

There was also these numbers, c95664 z, 6-10, c97372, and c96706k. Can anyone tell me what these numbers mean and what it came out of? Date ? etc??

I also purchased his 340 engine, it still had a vin on the side of "OR197483" Can anyone tell me what this was out of?? The date on it reads 11-19-68 or 69. Hard to tell. Thanks.
