69 Coronet Fender turn signal and Antenna Mast?

I am currently restoring a 69 Coronet and I am right before spraying the whole vehicle with primer. My only problem right now is the fact that I can't find out how to take off the turn signals that are mounted on top of the fenders. It seems to be totally blocked in unless I was to take off the fender, which I don't really care to do. Also, not sure how to get the antenna mast off, I have tried every way that I can imagine and no luck. Any help would be greatly appreciated! Thanks
