That is what I have seen, 3/4" wrench on that bolt, right?



Yes, the hex is 3/4.
The reason I ask is my dads original 67 Hemi GTX has the large headed bolt. The engine was out of the car back in 1974, and I was not sure if that bolt was correct. He felt sure it was, I questioned it because I don't recall seeing it on any other car. Yesterday I was digging through boxes of bolts from a bunch of 67 cars I parted out and ran across the same bolt. It sticks out like a sore thumb once you see one.

Guess I should know better than question my dad .

Thanks
