No such thing as a stupid question, just stupid actions because you didn't ask the simple questions.

 

There 3 different Electric Glides alone:
Electra Glide Classic FLHTC
Ultra Classic Electra Glide FLHTCU
Electra Glide Ultra Limited FLHTK


The “U” part stands for it being an “Ultra” model.
Which will include it having:
Lower Fairings (the part that blocks your lower legs),
King Tour Pak,
Rear Speakers attached to said Tour Pak,
a Headphone outlet for the front and rear riders,
an intercom system for said front and rear riders,
a CB unit,
you can also listen the radio through the headset hookup

 

I learned this little nugget from the factory guys and factory training:
XL (as in the Sportster) stood for eXperimental Lightweight

Also very cool of them to mention the FXRDG, very rare bike less than 900 made in 84. KUDOS
