So what is going to be needed to get this in my 02 wagon. Links to wear and stuff would be great too. I think the guy that is selling it they come with sliders already.

 

so its the seats and rails? good.

only small problem I can see is the airbag light. not sure but I think wrxs all have side airbags in the seats, so you might need a resistor for them so it doesn't trip it out.
