S15 Shift knob problems

[Soup Nazi]

Just bought an S15 Shift Knob, thinking it would fit right onto my S13 SR Shifter. Well apparently it doesn't.

The threads on the Shifter are skinnier than the knobs threads, thus the shift knob just "sitting" on the shifter.

What do I need to make this fitting properly? Couldn't find anything close when searching.

TIA

S13 = M10x1.25
S15 = M12x1.25

Get those small plastic pieces that increase the width but maintain the same thread pitch.

That would make the S15 the first Nissan shifter that was not 10x1.25, wow.
Not doubting what has been said, just surprised.

^^^ what he said.

when i changed to a 6spd i had to get rid of my old titanium knob from my 5 speed. but i do like the stock s15 knob alot suprisingly

Thanks, so far I'm trying to look for said adapter to make the width wider.

Anyone know any other ways I can use this shift knob? I'm having no luck right now finding anything that i can use to make the threads wider.

Might just have to sell it.

Fill it with resin and re-tap?

Try a helicoil.

Try a helicoil.


Just found a site Knob Adapters: Gennie Shifter and Gennie Shifter Knobs (http://www.gennieshifter.com/knobs-threadsize.php)

They may have what I need, if not the Resin and Helicoil will be my options.

Thanks guys

Any decent hardware store will have reducer bushings, you can drill/tap one out or just thread it on without threading, then force the knob on.

Thanks everyone for their Input.

Chris Mattessich from WC Lathe Werks LLC, has got what I need to make this work.

It's an extension, it will raise the knob up by 2" but thats no big deal....
