On an Olds 455, what size socket will or should fit to remove the connecting rod nut? I hat to say it, but I'm having the darnedest time to find a socket that will fit the nut and the space between the nut and rod.

Thanks kindly

 

9/16" 12 point socket. 3/8" drive.

 

Yep and a good quality thinwall socket...

 

Thanks guys. It's been a while since I rebuilt an olds motor and for the life of me I couldn't remember what I used to remove the rod bolt nut.
