It is an easy enough job, although I agree about dropping bolts - I did an never found the thing. I even got a boroscope to look in all the nooks and crannies!
I did mine before the blanks were commercially available - just saw off the shaft, remove the flap, drill/tap the shaft hole, plug with a suitable screw (Loctite'd)

Thanks Mike. Always appreciate your helpful response.
As old billy stated that new ECUs sense the position of theses and removing these may have some negative effects.
