The stock rails will bolt straight onto the n13 pulsar seats you may just have to enlarge the bolt hole slightly on the rails.
to bolt them into the car you will need to drill 2 holes further out in the driver door side seat mounts. The passenger side can be bolted in as there is enough play in the rails as they are a little taller to bolt them into the stock holes. Sliding functionality is the same as the stock seats. I think the seats i bought were about $40 each from a wreckers in very good condition. much more comfy than stock and a good option if you can justify the coin on a set of recaro or similar seats
end result:
