M45 grille

im sure this has been discussed many times before here and in other forums.
 
But i need some help.
 
if i order a Y34 Cedric grille, will it fit on my 2003 m45, or do i also have to do a cedric headlight swap?
 
also
 
does anyone know the sizes for the bulbs, of the rear, and front turning lights, and the side markers?
 
i need to find some LEDs that fit

search, i def remember glancing over a thread that covered all that,  what grille fits with what headlights etc..

you need to swap the headlights too, and for the bulbs check osramsylvania.com they have a bulb list for most common cars.
