NB 6 speed shifter
Sorta last minute, I decided to go 6 speed on my NA when I lost reverse in my latest 5 speed. I did not realize that I also needed the 6 speed shifter. I adapted the 5 speed one to drive around but its pretty stiff and makes my reverse lights come on with every shift, I unplugged the reverse switch. Does anyone have one I can buy or is there an aftermarket option that I am not seeing?

From Bill @ MR:
OP, just bring calipers if you want peace of mind.
No OEM bushings will let you mix/match without some modification. It looks like an MR custom (as specced in their kit) tip bushing will let you run an early shifter in a late car, but not vice versa.
For NB2 6-speeds, Mazda enlarged the OD of the tip of the shaft (from 15mm to 17mm) and the ID of the hole in the turret (from 19mm to 21mm) vs. all NA/NB 5-speeds and NB1 6-speeds which share the smaller dimensions.
...
To economize on manufacturing our kits, MiataRoadster uses the same 15mm size tip on all shafts and uses proprietary thicker-walled bushings for NB2 6-speeds.

So the junk yard sent a 21mm end instead of a 99 to 01 6 speed shifter with a 19mm bushing! They thought it was the same shifter from the same car as the transmission but they got switched around on the cars. And they can't find a replacement. So anyone have one? Again.

Did you get the stock height one? I'm thinking anything that looks significantly different than stock will not go over well when the wife drives it to work.

And I am horrible at making decisions. I just really need to get this car driving again. I have an event soon and the alignment it terrible. Probably out of time for a corner weighting.
