I'm also going to be redoing my current retro, I'm just gonna fix the cutoff and replace one of the headlight lenses and it will be for sale.
This is what I will be using for the new retro set
Mini Morimoto D2S Projectors
Mercedez E55-R Shrouds
Morimoto D2S 5000K Bulbs
Bixenon Harness
D2S Bulb Adapters
Here's a pic of the reflector, I made a 2 3/4 in hole on it.
