I want to cut the shifter down and cut some of the plastic off of the reverse lockout, but AFTER SEARCHING, I couldn't find what it would have to be rethreaded too. Maybe I didn't use the right words, but I'm hoping someone can tell me what it is. Also, any tips to doing it? Thanks

 

It is definitely M10. x 1 or 1.5 but I'm not 100% sure on the pitch
