What size bolt do I need for the bottom of the block on the drivers side... it's a coolant plug and I lost it when I took the motor apart

Not a bolt, but a tapered pipe plug. Though the book says it is a 1/4"-18 plug, it sure looks more like a 1/2" to me.

Remove your knock sensor and take it with you to the hardware store and match up a plug to it. It is the same size and thread.
