I've run my '95 ST with only the primary O2 sensor for about 3 years now. I used to get a CEL under specific curcumstances with a header and the stock exhaust. Once I got rid of the stock system and secondary catalytic converter, I no longer get a CEL. Mileage is 27-29mpg depending on circumstances, and I have larger injectors installed. You should be ok with running the single O2 sensor, if you can't get a boss welded in for the second one.
