Default Re: LT1 G104 Ground Socket Size?

Anyone happen to know the socket size required to fit the already next to impossible to reach G104 Ground Bolt on a '94 LT1?

This is the ground just above the Oil Filter on the driver's side, going into the engine block.

I'm trying to replace my negative battery cable - but am contemplating leaving well-enough alone on this one.

First hand experience NONE. BUT ..

I'd think 3/4 - I believe the bolt is 1/2-13 still and I doubt it a "reduced head" so I'd start there. Never done a - cable on an L98 or LT1/4, the LT5 is a Metric spec.

It is a 3/4" head. Should be able to access it with a box end wrench and/or a socket.
