I'd like to have the measurements of the U.S. Standard X-Bridge as I'd like to install it in my guitar.

I need the exact measurements of the baseplate and post spacing, both in millimeters.

I know the post spacing is 2.2" which equals 55.88mm, but would like to have official confirmation on the millimeters measurement since I don't know how accurate the unit conversion is. My guitar's bridge post spacing is 56.11 mm, very close, but I wanna know if it'll work.

Thanks for your help!
