Ford 8.8 Swap

Whilst in reconnaissance mode for exhaust manifolds in local yard, I spied two explorers: Photoed the vin tag on door.. compared to a chart (from local poster?) it showed 3:73 posi.. According that data, 3:73 was tallest gear available. Vehicles were ~'96 iirc or close.. What year would one look for a 3:27? (more what I want)

I currently have an 8.8 out of a 97 explorer with 4.10 LSD in a ranger. And it was stock gears.
