Howdy Silver......
I make "universal" shift knobs that fit the most applications. I use a master insert in all my knobs and supply threaded reducers to fit. If you have an automatic trans with the park/reverse interlock button poking out of the top, my shift knobs will install with the addition of an adapter as seen in this thread........

Scroll down to the post by NitroPT and note the first and last (5th) photos. His post shows a plastic "flameball" but my shift knobs attach in an identical manner. The adapter with knob attached actually plunges up and down to trigger the lnterlock release thus there is no button needed. This gives a very clean, classic appearance to the arrangement.
Let me know if you have any more questions.
