I kept reading from various sources 'on the stamp pad on the right side of the engine just ahead of the cylinder head' and I looked and looked and looked and did not see anything - found a head stamping that had something like PPO and 75 but that was on the head. Finally, I took some cleaner and sprayed one of the only flat areas I could find and, behold! numbers! And they match the car! Its a 78 L48 Auto - nothing special but mostly original and mine. At some point it went from Light Beige/Dark Brown to Black on Black (poorly)
