I was looking at the possibility of putting an Electra Glide OEM fairing on the Road King.

The main question I have is about the headlight assembly.

Is the headlight and assembly parts in the Road King able to be mounted on the fairing or would I need to get other parts?

 

If I recall the headlight bucket that screws into the RK nacelle should screw right into the fairing.

 

Before you go the E Glide route, take a look at the other gauges (volt, air temp, speedo, tach, etc) involved with the switch-over.
You might be better off, depending on your skill-set, going with one of the after market farings.

 

I have thought about the gauges too. There a few gauges that would be nice like air temp, tach, fuel, clock and battery.

 

Just to let you know that if you decide to go that way I have some gauges. I just traded in my '05 RK Classic that I converted into a Roadglide. I put it back to original condition before the trade in. I have tach, speedo, voltmeter, clock, oil temp, and oil pressure. I've been selling off the conversion parts and most are gone except some gauges and a Biketronics radio setup w/ amplifier. Good luck.
