Thanks Mel, glad to see you here!!
The biggest change is the v-twin engine and then a bunch of little things.
New tail lights
New steering wheel
New rocker covers
New dash panel w/tach
New HD shocks, added about 2 1/2" of lift
New rubber diamond plate floor
Lots of new paint (not the body)
Reworked rear bumper
I know there's more, just can't think!
