HELP! O2 sensors

I want to change both upstream O2 sensors on my 1996 F250 Crew cab 7.5L automatic. I want to use Motorcraft parts figuring they are the best suited to my truck. I think perhaps the sensors are the same but have two different length pigtails? Therefor different part numbers. What are the two part numbers I need. After looking at various part sites, I am totally confused... tia wiredgeorge (motorcycle guy)

You must be in California and have an OBD2 truck because otherwise your truck would be OBD1 and have only 1 sensor.

UPDATE! Had called the dealer and they told me I needed two upstream O2 sensors and gave me the DY1094 part number... WRONG. the plug is different and they didn't work and I only have ONE upstream O2 sensor. Hitched a ride to O'Reilley's autoparts with the old sensor and he matched me up. They had a BUNCH that were supposed to fit but the gauge of the wire and thus the contacts in the plug and the conformation of the plugs were all different. Finally got the right one and got it installed. Ford apparently has used bunches of different O2 sensors so best to actually look up under the truck and see if your 96 F250 7.5 has one or two then remove one or both and take them to the autoparts store and just buy Bosch like what was recommended. Pay close attention to the four metal contacts in the plug as well as the plug itself (DY1094 were just too thick).
