With a standard socket, that particular tool will not fit between the bolt and the frame. (Although I think you can remove a motor mount to get better access, but that involves a lot of work since this motor mount is attached in a few different places, and that also involves jacking under the oil pan with a section of wood to support the engine while the mount is removed.)This type of SB tool isn't any help? It's what I use. Moving the power steering reservoir (without disconnecting the hoses) isn't hard.
@Wildcat, Is it like the Snap-On tool?
