and will these shift ***** fit:

Classic T-Handle *****
Smooth and comfortable are the name of the game with these T-Handles. Choose either the brushed or chrome finish, both have the embossed B&M logo. Handles with the button make it easy to activate any line lock, transbrake or nitrous system without having to remove your hand from the shifter. Works with 12 or 16-volt systems. Includes thread inserts to fit 1/2'' - 20, 3/8'' - 24, 3/8'' - 16 and 5/16'' - 18 thread shifters.

Hammer Head T-Handle *****
The same ergonomically designed handle featured on the Hammer shifters. Fits your hand comfortably and features an Chrome plated aluminum finish. 130-80741 includes adapters to fit 1/2'' - 20, 3/8'' - 24, 3/8'' - 16 & 5/16'' - 18 thread shifters; 130-80742 fits 1983-96 Camaro/Trans-Am 16mm x 1.50 threads and 1983-96 Mustang 12mm x 1.75 threads.

 

I believe they are 10mm x 1.25mm thread pitch (at least that was the Miata size, and my Miata ***** fit my RX8 just fine).

 

s0 are these going to fit it?

 

You do know that ALL the T-handle shift ***** that B & M makes are designed for AT?
Not one T-Handle in the MT shift **** section.

To answer your question I don’t think the Hammer Head will fit. They do carry other T-handle’s in Metric the 80550 & 80551

but again you are planning to use an automotive part for something it was not designed for. Good luck, rigging things can be fun but I wouldn’t do it with something as important as the gear shifter.

 

That is the thread size listed by Team Voodoo as being for both the Miata and RX8.
