Every seat in any car I've ever seen is bolted from underneath. You will have to reach under the car with a ratchet to remove them. You shouldn't have to remove the seat but with the bolts removed, you can just rock the seat over far enough to look under it. Good luck finding your wallet.
I don't know about station wagon seats, but I've yet to run across a mopar with a bolted in back seat bottom.
Front seats, yes. Back seats, no. Whether it was my 51 Plymouth, 65 Cuda, 87 Diplomat, 96 Neon, none of them had a bolted in back seat bottom.
