fever, executioner, lightning
 

I was wondering what the differences are between these 3 models are? They all look almost the same.

Lightnings/And Executioners have a walkaround lightning has twin steps from 99 up, 95-current executioner/lightning old school look single step squared windshield. 1990-95 lightning no step hull looks the same as a executioner35-38-42.fevers no walkaround 27-29-32-36-38

What about construction? Are they layed up the same?
