I've played with Mopars for a long time. My experience with seats was that the 60s through the early 90s seats would swap along car lines or body styles, and the trucks would swap Dakota to Durango, and Ram to most full sized Dodge trucks of the same era.

Past the early 90s, lots of stuff changed. Until you run across someone that has had both seats from the same year/body styled vehicles apart, you won't know until you try it.
As listed above, seat brackets from a 97 Ram didn't fit a 99 Ram, who knows if the seats would have swapped on the brackets. Back in the old days I would have said yes, but these are not the old days. Too much stuff is body specific, model specific, and year specific. Gene
