I tried it, but you need a headlight closer to the design of the newer vehicles. If your glass is cut or molded, the LED lights do not work correctly. You need clear glass.
You can buy a few brands that have clear plastic/glass and they will probably work fine. On another note, there are some pretty hefty halogen lights out now like these:

They are amazing although life is a bit short, but on a Cobra, that might be 10 years worth of driving.
