I bought a standard flex head ratchet that was way too big and did not come close to fitting between the firewall and the Torx bolt. I then ordered a closed end ratcheting "Gearwrench" Torx wrench that fit fine but was way too short to generate the amount of leverage needed to budge the Torx bolt. I could order another longer wrench but I've had it with this project. I'm not going to get into dropping the transmission so I am towing the car to a local starter/alternator repair/rebuild shop and have them take the starter off, rebuild it and reinstall it. I'll have it towed back and I'll hook everything else back up. Some real moron designed this - Torx bolts and facing them the wrong way, requiring you to remove a multitude of parts including the intake manifold to get to it!!
