Steve- \\; You might want to get an all rubber low profile one...believe they sell them at radio shack and a couple of other audio/car stores. \\; My buddies have changed out both the Ultra and FLHX ones with all black rubber onesthey look better to me. \\;
don't know about the 96, but on my 06 Ultra, I can take out the inner liner of the tourpak.. the cable coming from the radio has a knurled fitting that screws onto the antenna base that then is attached thru the tourpak.. the visible part of the antenna shaft then screws on there.. \\; and that part is replaceable
The antennas on a tour pack (At least the one on a classic) have a mount that is a threaded shaft. It has threads on the top, where the antenna mounts and a hole that the antenna cable mount is screwed into. It is replaceable but you will probably have to get more than one part.
My antenna broke off like yours did and I found all the parts necessary in my parts book. You do have a parts book? Right?
