Hi and thanks for using 2CarPros. Com.
I was unable to find anything that lists step by step. However, I will do my best to explain.
First, there are three parts to this assembly, the mast, top mount (exterior of the fender) and under that (cannot be seen is a threaded mount which is not welded to the fender).
What you need to do is remove the inner fender to access the threaded mount while you turn the top mount to loosen. The two parts will come apart for removal. Once apart, remove both items. New ones should be included with the new antenna.
I wish I could do better for you. If you look on line for universal replacements, you will see how the two parts bolt together. The worst part is you cannot get to it until the inner fender is removed.
Let me know if this helps.
