I don't see any real issue with the explorer belt routing, it's just different than the Thunderbird. I think they have the AC compressor up top, but as long as it fits under the hood, shouldn't be a big deal right?
I was googling it up, and according to what I've found, the compressor is still bottom passenger side. The only difference I've seen is there's an extra idler on the driver side.
