I just happen to have a TB blade laying around 
I'm assuming it's the TB blade you mean (butterfly)....
It's kinda hard to tell with a basic ruler but it looks to be 2 15/16". If my conversion is correct that's about 74.6mm.
As for the TB bore where the blade seals, I'm not sure how I'd get an exact measurement. But judging by the blade diameter it's probably 75mm
