/6 904 rebuilt never used/installed transmission and lock-up torque converter for 68 and up

The /6 the car came with threw a rod when it was my daily driver and I had a local mechanic source a replacement. Maybe the motor was a much later 1978+?. The mechanic never said he needed to also swap the torque converter and / or transmission.

I gave the trans and torque converter I had to the guy who rebuilt it and so if these are not correct for a 67 /6 car should I relist it for 1978+ ? Thanks for any advice. I am not looking to misrepresent what this is.
