X2 on the above suggestions. A few other tips I have heard and tried are first have someone guide the extension and socket in place through the shifter cutout hole in the floor. They can usually see the bolt heads through that hole. Or a body lift, even 1", can make access to those bolts a snap. What I found is that with a mild body lift, you can both see the bolt head and manuever the socket onto it at the same time. Without the lift, you have no clear view as the socket moves in.
