I bought the seats to replace my back-killing original seat. I picked them up from a Recycler on EBAY. They were about $300 +$100 to ship them from the east coast to Nebraska. It's kind of expensive for a seat but the old one was killing me and a custom aftermarket one was $700+. They bolted right in with no mods. All I did was run one power wire for the power lumbar/bolster.
