Yep, I'm actually going to do the cap, rotor, and wires.
How about this from 2phast's site:
Although I don't have any pictures of this, the O2 sensor is a three wire Bosch unit that the dealer wants over $200 for. After some careful research, I found that the 1990 Ford Mustang 5.0 uses the exact Bosch 3 wire O2 sensor, but with a different plug on the end. I bought the Mustang O2 sensor for $36 and cut the plug off my old O2 sensor and spliced it onto the new O2 sensor. Works perfect!
What do you think / how would one verify this?
