[quote="a.k.a"]I was always under the impression that the notch was just cut out of the ones fitted to the original 500s, but I recently bought a genuine 500 lower fin and the missing bit is 100% moulded in, as you can see the mould line and the walls of the notch are perfectly smooth not cut.


i was just about to say the same,i have a 2.0 spoiler on my 3 door,and got a genuine 500 one to copy the cut out (it was from spadges black 500 he bought a few months back) and the spoilers are very slightly different were they sit on the rear quarter,but for £20 ,i can live with it.i have seen some right bodges ,were people have tried to cut the 'v' out
