My TWM weighted knob came in today (took a month). Those of us who have a katech short throw shifter know it is damn near impossible to find a good knob that is threaded and fits. If you order a TWM knob in a 9/16-18 thread pattern the insert can be bored out and retapped to accept the katech shifter with minimal effort. Took me all of 15 minutes:

1. I used a vice to hold the insert in place
2. Drilled the insert out with a 1/2 inch bit
3. Insert lock nut and insert into knob
4. Put tap in vice, and twist knob until insert is fully threaded.

The TWM knob has a very solid and connected fit, well worth the wait and 15 minutes of labor.

Nice! Is 9/16" the size that accomidates the stock shifter?

9/16-18, it is the easiest to modify because it is only off by 1/16 of an inch. Still has to be drilled out and tapped, but that is the size I ordered.

edit: I have no clue which one fits stock shifters, this was for katech. I'm not sure what the stock size is.

This is why the Katech shifter comes with a 5/8-18 tap included so you can tap the factory shift knob or any other knob you want. Why not order your knob in the correct 5/8-18 thread?

Well furbe...go ahead and find me someone who makes a shift knob in that size, also try to explain to the canadians who run TWM that it would be worth making an adapter in that size. in fact.

eBay has knobs in the size needed for the katech. They are just standard round ball knobs like the hurst knob but look nice for the money.

Reason I'm asking if the stock size shifter is 9/16 because I'm looking at a used CTS-V TWM knob and I have a katech shifter.

The stock shifter is not threaded, the shiftnob snaps on. This is why Katech includeds a 5/8-18 tap so you can tap threads into the stock shiftnob. (or any ball knob or handle of your choosing.

I called TWM, dude said although they do not show 5/8-18 thread as an option on their website, it would be no problem to thread your custom order ball with this thread size. Just call them.

I know stock is just push on but it's the diameter of the shifter I'm still interested in so I will know if this used knob I'm considering will work for me or not? It's ordered to the fit stock V shifter.

The whole point of this thread was to show that the fitting's TWM uses can be drilled and threaded. TWM does not make a shift knob that is threaded to a certain size, just an insert. This insert has enough meat on it to be threaded to a katech short throw.

I know the point of the thread but without a drill press, I'd prefer to not have to take much off the sleeve to make it easier. That's all. I know any size can be drilled to fit.

I don't see why everyone thinks Katech uses a uncommon thread. Its the same thread used in F-bodys. There are lots of shifter knobs available.

Are you sure about that? I've searched and haven't found shit for 5/8"-18. Only a couple options and I found some basic machined billiard ball style knobs in steel and stainless on eBay threaded to fit already.

I just got the TWM piston knob I traded for and I'm trying to install this thing. Says u used a 1/2" bit but my insert is already a larger diameter than that. 1/2" bit slid right in with space to spare. The knob insert was made in the diameter that fits the stock shifter whatever that is. The tap that came with my katech doesn't fit in the knob but it's close so it looks like I'll just have to tap it and be done. I'm hoping so anyway but I may take it to a machine shop and have them do it. I don't have a vise and I don't want to risk tearing it up trying to tap it for install.
