Sway Bushing Sizes - 28.5 or 30 mm
 

I want to get polyurethane sway bar bushings from Energy Suspension, but I want the greaseable ones.

Know that Ranger swaybar sizes are all over the place for some reason. My 06 FX4 I measured out to a 92 mm circumference, which breaks down to 29.25 mm. I'm guessing I am off a bit, so we'll say I'm 29 mm.

They sell greaseable only at 28.5 and 30 mm: energysuspension.com | Sway Bar & End Link Bushings

They do have non-greaseable at 29 mm, but maintaining them would be such a PITA.

Has anyone gotten the 28.5 size for a 29mm sway bar and been OK?
