I marked the centre of the tremolo on the roller and down the plate to the back, and then I lined this up with the wire moving the tremolo around with its hinge plate against the back of the guitar until all points were in line.
Now installed, strings all in alignment and looking good.
I think this is how Bigsby tell you to do it.
