Chrome shift boot cap mod

So I recently installed a URD short shift kit on my '15 Tacoma which I'm happy with (no more boat rowing to get into 3rd and 5th) and ordered a grey TRD shift knob (undecided on whether that massive knob will stay or go) but now that the long stock shift knob is gone, there's a gap between the chrome end-cap of the boot and the shifter. Anyone have a solution on how to cap that cleanly without just painting the louvered chrome cap a black that matches the now exposed shift rod?

 

Black rubber washer? One underneath to hold it up, and maybe another on top to block the chome?

 

Saw someone cut a piece of black tubing or pipe to the length between the ball and the boot with a rubber washer on each end it looked good. the tubing was thicker than the shifter and made it look more like it was stock.

 

I got a sink gasket at Lowe's and superglued it on the ugly chrome piece.

 

Awesome! Thanks guys. I'll head over to Home Depot and see what I can piece together

 

I bought a washer and a small pipe, and put it over the shifter, under the knob. I painted them both black as well to blend in. I can post a pic in a hour or two.

Edit:
Here is the pic:


If you want me to get a better one, let me know, as I was trying to get the shift knob more than the cover I made.
