I strongly suggest you buy yourself the seville 4.9 engine mount and pull your existing mount. Once you do this you will see exactly what needs to be done. I cannot comment on the easiest way to accomplish the modifications with the engine still in the car as I have pulled both the engine and transmission in preperation for my series 3 supercharged swap that is underway. I suspect you could get to this area after removing the radiator, fans, and a/c compressor. You may not have to do all of this, I am purely speculating. Worse case, you could visit a machine shop and have the seville mount cut open, the studs flipped to the proper position, and have the bottom of the mount welded back together. Aftermarket Seville mounts sell on ebay very reasonable...
