OK, we'll try to keep this brief...

• Unfortunately, we have no way of knowing all vehicle shifter thread patterns and sizes, so we leave it up to YOU to know or obtain the measurement!  If you're unsure, you can take your current shift knob to a hardware store and they should be able to help you size it. 

  This is as a guide only, and no guarantee that it is 100% accurate (please check your own size), but this is info we gathered that may help. 12mm x 1.25mm: most Toyotas, Subarus and newer Mustangs 10mm x 1.50mm: most Hondas 10mm x 1.25mm: most Mazdas, Nissans, Mitsubishis 8mm x 1.25mm: most newer R/Ts,  05/06 Magnums, Chrysler 300s, SRT 8s 3/8": 1989 Cobra  5/16":  Gennie shifters 3/8-24: Lokar

• Most knobs come with a 16mm master insert.  We offer one of the thread adapter kits at no extra charge with the knob:

One kit is included with the knob at time of purchase.

The standard kit comes with one each of 1/2-20, 3/8-16, 3/8-24, 5/16-18 reducer and jam nut.

The metric kit comes with one each of 12mmx1.75, 10mmx1.50 reducer and jam nut.

• We do not make these shift knobs, but we work closely with the manufacturer for the best quality possible.
