99 Durango seats for 78 K10 Stepside

[Gorehound187]

Hello all.
  was at the pick n pull today and found some seats in a 99 Durango that look like they might work. From quick measurements, they should clear the steering wheel just fine. Question is with the way they are mounted lower in the back vs. almost level in the k10. how much modification do yall think it would take?(srry,tried to post pics, but cant shrink em small enough from iphone)
