Shift knob won't stay on, What's the fix? Options

I noticed my Rennshifter knob has 2 small set screws (IMG:style_emoticons/default/smile.gif) l

The shop I went to is a well-known indy Porsche shop in my area. They probably had thirty+ vintage Porsches on the premises, though mine was the only 914. Mostly 911s and 912s, with one authentic 356 in the mix. Aren't these knobs the same as on any 911 with the 901 gearbox?

Yup same.

All the more appalling that some Goofus was suggesting you need a knob with set screws. (IMG:style_emoticons/default/chair.gif)

Actually, I have found that the only solution to fix a loose shift knob forever is to drill a hole and use a set screw. It will NEVER loosen under normal driving conditions. When done properly, with a hex type screw, it is practically invisible. Guess I was the "Goofus" that suggested this in an earlier thread on this topic. I still stand by it.

A Goofus is the guy that works at a shop that should know better but uses electrical tape on a paying customers car while bad mouthing the OEM part they didn’t install properly.

You’re fine! (IMG:style_emoticons/default/beerchug.gif) (IMG:style_emoticons/default/laugh.gif)

All good suggestions here. I discovered long ago that I was gripping the knob too tight while shifting. Loosen your grip and you'll be able to guide the shifter from gear to gear.

Good to know. I'll give it a try. Thanks.

I have been shifting with a loose knob for many years with the red 3.2. Recently I realized that I have a short shift aftermarket stick. Which may indeed use the aforementioned set screw. The nice mahogany cloisonné knob on the ‘76 indeed uses a set screw and that car has a short shift kit. Just thinking maybe you have a mismatch of some sort. What these cars get into during their lives before we met continues to amaze me.

I appreciate the input. Actually, the car had some kind of short shift in it that I hated. Too short. I had to lean over and down to shift. No leverage. I took that out, installed a used OE shift stalk and an OE style knob. That should match.
