Anyone know if you can just change the side mirror covers of the 13+ to a 08 without having to change the whole assembly?

 

I suspect not for a coupe of reasons. First of all, they have the direction indicator lights which, obviously, wouldn't work without additional wiring. Secondly, the shape looks different to me, more angular (from memory - I no longer have the '07).

 

No...however, you CAN upgrade your 08 to those looking more like the newer LS's as many of us have done. Have a look here:

Thanks guys
