Can anyone tell me the sizes in (mm) for the front and rear sway bars of a stock 95 v6 3.4? I'm going to replaces the bushings but I don't wanna get the wrong size. Also I was thinking of getting bump-Stops, which ones should I go for?

 

OEM should be 28mm front, 15mm rear -- you can measure them yourself with a cheap vernier caliper. I would go with poly endlinks/bushings.

OEM bumpstops provide the smoothest transition, aftermarket poly ones would be more abrupt (harder material).

 

That's what the stock were on mine when I measured them before upgrading to SS sways. I would suggest spraying the bolts and nuts with some kind of penetrating oil before, because those kind of parts like to break at that age.
