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)

we dont know what year it came out of, it came with a bunch of parts my friend traded, we used the 8.8 cause it was the perfect width for his 48 dodge and had rear discs, 3.27 gear openOLOR]
