You can't eliminate the front o2 sensors. They are required for the engine to run properly. The 94/95 Mustang GT ECU will run the 4r70. You may have to swap some sensors and solenoids for the 94/95 Mustang ones, but it will control it. The problem with running that ECM in a 97 is that you will be doing a lot of re-wiring, because your car is obd2, and the Mustang is OBD1. You would basically have to first rewire your car as a 94/95 3.8 tbird, then modify it from there for the Mustang ECM. A custom tune is not that expensive, probably around $350, and in addition to making your life easier, it will add some performance as well. As for the belt, if you can route it properly with a single shorter belt and the spring loaded tensioner, there is no reason not to.
