I’ll just add that having worked on cars for a living, both in auto body & as a mechanic, have run into issues and differences with this.
Have a few different bits t47, t50, etc., and I just use whatever fits best.
I removed and replaced all if mine in ‘94, and removed all from a ‘96 parts wagon using my t50 bit. A t47 was too loose, but would’ve worked being careful. My t50 is a Matco, and I have 2 or 3 different t47 bits all different manufacturers.
