Power Antenna

Now to replace the power antenna as the mast is bent and will not retract all the way.

A few questions:

Will a generic power ant replacement work or is there something special about the SVX one?

Are their any special tools or tricks to get the old one out?

I hope this will be the easiest of my projects, but probably not, its a SVX not a Chevy!!

Hoping to hear reassuring ideas!!

Thanks!
