Looking for an aftermarket shift knob with same pattern but allen wrench mount instead of the crush bushing. I have a rebuilt shifter getting installed and wanting to use a more solid shift knob. Also, what is the diameter of the OEM shift knob? I had a old 911 threaded shift knob but no way it will go over the 914 shift post, the 911 knob diameter is way too small.

Thanks all.

I don't remember the size, but the momo shift knob worked great and used Allen screws. 911 and 914 are the same size shift knob.

I like mine from here. feels great in hand. they have 5spd pattern too.

Do you have any contact info at nirvanamotorsports.com. I want to buy a shift knob for the 901 trans

I've had great luck with crush washer-mounted knobs. For me this is what I'm running in case you haven't closed the door on crush washers...

From Vacca Rabite, nice feel, excellent craftsmanship, very nice feel in the 914.

From a machinist friend who custom turns out of stainless or aluminum, this is stainless, nice heavy feel and comfortable for the 911 shifter position.

Try Luka at www.function-first.com as they now have 5 speed 901 shifter knobs. Tel 973-229-9331. Great looking product. Pricey however.

I came across this a while back. You can get the knob in different colors and the shift pattern writing in different colors. You'd have to get their set screw adaptor for it though. I like the shape of it. Reminds me of old 50's-60's VW shift knobs.

I just drilled and tapped the base of the original shift knob for a 4mm allen screw.

Be careful. . the original knobs were made from Bakelite, which is very hard but very brittle. . It has a tendency to crack at the lower thin edges. .
I have remade a couple with a brass sleeve insert to increase the knobs lower strength and also have a closer fit with the shift handle. . even on those the thickness of the brass sleeve was less than .030. .
My experience is even with the tightest crush sleeves, the knobs can be twisted with
minimal exertion. . a solution is to drill a locating hole through the knob and into the shift arm, Then tap a thread in the steel arm, not the brittle bakelite, and use a very small allen head set screw.
