Your comments about the 68 antenna apply to my situation and I am hoping you can offer some guidance. The antenna mast on my 68 is broken off about two inches from the fender. Using terms I fond on page 163 of the latest Ames catalog, the antenna base nut, the antenna base adapter and the rubber mounting pad are all still present. I can tighten the assembly down on to the fender using the base nut. Is broken piece of the existing antenna mast supposed to be able to be pulled out of the assemble? According to what I can see in the catalog diagram and the pictures of replacement masts, it looks like that is the case, but my attempts to remove the broken stub haven't worked, maybe just not enough muscle? I didn't want to force anything so haven't used too much in the way of force. Thanks in advance for your help!!!
