I simply use the conversion housings sold all over on Amazon for about $20 a piece that accept the H4 LED replacement bulbs.

For LED's I prefer the Lightening Dark LED's also sold on Amazon for about $50 a pair. After using several they are the only one's I've come across that project a very nice beam.

So for about $100 you can have very bright LED headlights that work fantastic.

I've converted the Chevelle, the Firebird, the Camaro, my sons Mustang, dad's GTO, and will likely do the Nomad and the Vega at some point. No modifications necessary on any of these cars.
