Replacing starter

My daughter has a 1996 Lincoln Towncar with about 120K miles, 4.6L V-8 and is a rear wheel driven car. My problem is replacing the starter. I can remove the two electrical connections without any problem. I can remove the lowest bolt holding the starter body to the bell housing. But I can not get a tool on the bolt just above the solenoid and the bolt on the upper part of the starter body.
Please keep in mind that I am flat on my back under the raised right front corner of the car sitting securly on a jack stand. My tools consist of a socket and wrench sets (both metric) - no powered tools here!
