Gear Shift knob Options

[stickyfingers]

Hi all. First of all I love this forum. I'm really appreciating all the help everyone has been giving. This community is top notch and without judgement.

I'm finding all these small challenges with the vehicle but working through them one by one. This question is related to the shifter knob. Mine comes right off while driving - kind of annoying and dangerous at times. Seems like the previous owner put in two sided tape in the inside of the knob to kind of keep it in place.

I have checked the screw attached to #2 in the attachment below just moves around - not really thread it in there. I removed the screw but cannot seem to remove the #2 piece - don't know what we call that. Sorry for being such a noob.

Question 1: is there a way to remove that?
Question 2: should I just put some gorilla glue in the knob to hold it in place (lol).
Question 3: Should I buy a replacement (I love the existing knob) - see pics.

Searched previous posts and saw that people are suggesting I put a towel and slightly hammer a wrench upwards to remove that bushing (held by the non-working allen screw). But not sure if it will solve the issue. So just looking for your guidance on what is the recommend option.

Again, any help would be greatly appreciated. Thank you!
