Thanks Simon. Yeah I figured the half mm should hopefully be safe. The body is deep enough to take the new studs so that's a bonus.
I'd never thought of how the force is distributed. Thanks for explaining it. I think I'll do some measuring today to check the scale length to make sure the bridge placement is spot on. Otherwise I'll probably have to plug the existing holes and redrill. But eyeballing it, it looks like it sits in the same place pretty comfortably.
Here we go!
