I can see your concept with the gear knob - I've been looking at the MOMO Heritage gear knob which is a similar style. Check it out as the MOMO has a leather top which (might) match your leather...
Maybe a longer leather gaiter, or (a brave pill and) cutting down the shaft would close the gap... In my humble opinion it is better than the standard one and might be better attached - mine is loose already.
Your new knob would look great with a wooden dash too.
The grip tape makes a huge difference in the wet!
Yeah I thought about cutting the shaft for about half a second, and then promtly slapped myself on the wrist 😂.
I've ordered a brushed steel sleeve nut on ebay to close the gap. And I might try and drill the knob a bit more so the shaft goes in further. I've also ordered some tungsten heavy putty to try and stuff some inside the knob to give it some weight. Worth a try as I'm probably going to swap it back as it is now.
