Crown vic 98 swaybar bushing size

I have a 98 Crown vic police interceptor and i need to change the front driver side sway bar bushings but i cant figure out the size can anyone help?

Measure it.
They’re talking outside diameter. ( Cheap plastic calipers available in a woodworking catalog, leevalley.com, has both metric & u.s. on one. )

( In the parts book it suggests the 29.5mm one has a bit of bend in the mid section and the 28.5mm one is straight across. )
