i did this mod last week, i didnt know the part number, asked the dealer and he brought up a pic in the parts system, showed the spaced out leon
badge on the rear, ordered it.
when i got it it wasnt spaced out correctly for the either the one i wanted to do (spaced and centred) or for the one i had already, close together, bottom right of the boot.
one of Pabs guides has a pic of the correct spacing, has all the measurements, between each letter and from the edge of the boot, looks ver good once done, ill have to get some pics up once its clean.
ill say though, i am having a few problems removing the glue form the set of decals that i removed, tried hot water and soap, nail varnish remover, the lot, still little remnants left over lol.
