would these be a direct replacement?

No it wouldnt be kirst. Check out FAQ. You will need to change the whole front end and alot of wiring.
Few guys had a look at doing it, bill was over £3k. Phil a member on here is doing it though
 
oh right thanks i dont have that much to throw at my car.
 
if i changed it to the sline front would this mean just getting new fog light grills fog lights and connectors?
 
sounds a cheaper option just need to find a bumper in phantom black in good condition.
