Hey, not sure what seats would be compatible with my ‘03 Honda Civic LX

I seen some 2012 Civic Si seats that are being sold by someone selling parts of their car. This might be a dumb question but I was wondering if they would fit , or if I’d have to do some work to get them to fit (switch brackets, weld, etc) or . If they don’t, maybe anyone here has some ideas as to what car models seats might be compatible with mine.
