Good chance you won't find it. When your Formula S was new years ago and had it's engine go bad, no one could have known what it would be worth today and save the block. Back then it was just a car that needed a engine.
It would have been noticable to stamp the pad knowing the car was built in October 68 per the fender tag and the pan rail has a stamping of 4/69!!!!! I still feel like it is legit enough!
