I installed dodge neon seats in mine, no welding, just bolted the new seats to the old sammy rails. If I had it to do all over again, I would make sure that the seats were out of a 2 door model if they made one, these came out of a 4 door and don't flip foreward to give access to the back seat area. I don't use the back seat so it wasn't too big of an issue, but it would make it easier to get stuff out.
