Well actually I bought aftermarket ones off ebay and still have the stocks sittting here in my house. If you put the headlights in the oven for 7 min at 260-270 the butyl rubber gets soft and you can pull the lens apart from the housing. I tried it on my stocks and it appears they have a silicon bead instead of a butyl rubber. After 7 min in the oven the stockers wouldn't pull apart for me. The headlights I got of ebay were $138 and came right apart. Then after building in the projector you just reseal with more butyl rubber and your done. Still no leaks of moister in the headlights and I have washed them many times and been through rain many days with large temperature differences.
