1955 Olds special bolt
#6
The IDK bolt looks good but would like to have the 3/8 on the bottom and the 5/16 on top. Sure would like to find the stock bolt but top end of engine was torn down when I got the car. If no luck finding it might have to weld 5/16 piece of all thread on 3/8 bolt

You could drill and tap the 3/8 bolt head for 5/16 thread and make a 5/16 stud to thread in and lock it in with red lock tight. I would not drill very far into the head of the bolt to make sure you don't degrade the bolt strength.
