That type was not the AMCO one more widely sold by dealers, but from the period anyway.
However, it looks like the threaded type down in the hole, which IIRC was used on some 356s & early 911/912s with threaded shift shafts. Not sure it will fit on your shift shaft, unless it is threaded.
Crush Sleeve & a repro 901 shift knob are shown at this link below from SMC, but other suppliers may be better sources nowadays.
http://www.sierramadrecollection.com/914-9...-86-p19751.htmlI don't know what you paid for that knob - which is a painted vs. cloisonne crest, but if it doesn't fit, then I think AA sells a newer cloisonne version with a black trim ring for not too much, plus Porsche Classics is making the original 901 5-spd pattern ones new again & available from dealers & other parts houses like Stoddards $ Einmalig for about $175 IIRC.
Sometimes the original AMCO cloisonne crest ones in walnut to leatherette come up on evilbay for not too much in good used to NOS condition as well.
It would insert into the hole to fill the gap tightly when pressed onto the shaft.
Look for the Porsche crest cloisone (which is essentially baked glass) & its surrounding metal ridges separating the colors in the best possible condition without chips, cracks, oxidation of the metal, etc. - & the leather/vinyl can be not so good - since you can get a local upholstery shop to recover it, along with your steering wheel leather (or at Dallas Steering Wheel) & the leather shift boot (if a center console 914) - all in the same leather.
Personally I like the look of the crest & can remember the shift pattern just fine!
BTW - I could never just pull my knob off as Mark/914sixer said, but by just tapping it off with my "U" wood bit described above usually worked it off cleanly. I just was being facetious when I said "banging" it off above.
Good Luck!
