'97 s10 with 2.2 liter 4 cylinder. This is driving me nuts. There's a straight shot from under the truck to one of the flange bolts, but the other is blocked by a frame member, the exhaust pipe itself, and a number of other things under the truck. It's also inaccessible from the engine compartment. Anyone have any pointers regarding how to get a wrench on this thing so I can replace the gasket and get rid of an exhaust leak?

Thanks
