The weather finally decided to give me a chance to give this thing a tune-up. I honestly think it's quite possible these are the original plugs, and I know the wires are original. Just a little note (I will post this in the full size truck forum) that you can indeed use plug wires for a 96-97 Mustang on these F150's. They are a little shorter, but really quite manageable. I bought the Motorcraft WR-5938 wires, and used the Motorcraft SP-432 (AGSF-32FM) Finewire Platinum plugs. The threads were much longer on the new plugs, which caused a panic at first. Then I realized the seat was in the exact spot as the original Motorcraft AWSF-32P plugs (they no longer make these from what I understand). The plugs I took out all gapped out at .64 to .85 - not good for my MPG's.
Here's a couple photos of the plugs I pulled out:
The electrode is deteriorating (melting) on this one:
Look at the gap:
