Subaru OEM Titanium Piston Shift Knob Adapter/Insert

Hello there,

Do you have a STI OEM titanium shift knob (C1010FA100 specifically) that you want to run on your 5 Speed Subaru but the factory plastic insert is stripped? Well look no further. This seems to be a common problem with these. I have a few variants, M10x1.25/M12x1.25 and printed threads/designed to be tapped. This insert may work with other 5Spd OEM options shift knobs too.

I am currently running this part on my Miata no problem. I wasn't able to test this on my WRX before a 6spd swap. Please leave feedback and I can tweak as needed. Thanks!
