The side skirts come off easier if you slide them off the clips, then unscrew the clips from the mounting studs. Figured that out after I broke a bunch of clips....
Never did get my antenna off, it just wouldn't unscrew so I lifted the whole front end up over the top of the antenna (good thing it is flexable) probably why my radio doesn't work too good. I quit before I broke the antenna off.
Did my front end on the grass so it had something soft to rest on, It helps to have an extra set of hands when it comes to removing and reinstalling the clip.
