84-96 floor pan in a 97-01

Does any one know if a 84-96 replacement floor pan will fit a 97-01 body? The drive side of my 98 is going bad and I would like to repace it with a new one before it gets to bad. I would just weld in flat stock but I don't want to cut out the whole thing just to repair it around the rotten beads.

The seat mounting holes are different, otherwise should be the same

The firewall changed dramatically between the models but the sloped footing areas should be identical.
