The switch in the 6-speed shifter-related design ('early' vs 'late') happened in mid 2001 at VIN 220739.

Your 6-speed's VIN is early style. So you need the middle shifter.

The top shifter is for an later style 6-speed. The bottom one is for a 5-speed.

JKav, thank you!!!! I knew about the changes on the shifter p/n's but could not identify them, really appreciate it.

Thats quite an odd thing to know.... But you definitely get props for knowing that!!!!!

Yeah, damn, props to you.

I only know because I recently had to research it myself. Long story short, anybody need a brand-new, 'early style' 6spd shifter? Cuz I have one that I can't use...

Yup, props to you. Was checking out the thread to potentially post the same info as I also had to go through the same thing with mine.

Did Miataroadster do anything else than a larger tip bushing to be able to use the same shortshift kit for early and late 6speeds?
If that's the only difference you could just buy a hybrid bushing (small ball but larger Od, "shaft tip 15mm D, turret hole 21mm D").

I may need a NB1 6-speed shifter.

Just to help people out with the identification, 6 speed shifters are 3/16 shorter between the big ball and the small ball, and the big ball is bigger on the NB2 shifters. So:

NA 5MT: long shaft, small ball, one slit
NB 5MT: long shaft, small ball, two slits
NB1 6MT: short shaft, small ball, two slits
NB2 6MT: short shaft, large ball, two slits

Now we can all consider ourselves experts on shafts, balls, and slits.

Sorry to dig up an old thread but, does anyone have approximate measurements of the balls? I pulled a shifter from my 6 speed and something doesn't seem right. My ball (I'm a one ball man and I'm off the rodeo...) measures 14.92mm, and the control rod end it goes into, without a bushing fitted, is 15.18mm. Does that sound right?

Sorry about this, I had a noob moment and measured the wrong control rod end. But, between myself and the seller of the transmission I have (who is a stand up guy up in El Monte) we came up with some measurements.

90-05 5 speed shifter with bushing: 18.75mm
99-00 6 speed shifter with bushing: 18.75mm
01-05 6 speed shifter with bushing: 21.5mm

I hope my mistake can help someone else out in the future.
