Crap I'm wrong on year, sorry I'm way wrong mine was 65, that is my fault. I was not paying attention to my own post. My tranny was impala 65 not 69. I apologize. My partial Vin was S2 it didn't have a number before it, it was the casting case numbers that determined mine was a 65. Foot in mouth, thanks Bertfam side note this was the trans in my 67 Camaro, I have since sold to intstall a date correct 67 m20 in my camaro
