new bushings

looking to change out all of my bushings on my suspension components. anyone know where i can get a good set of poly bushings and the part numbers??
and also what size front and rear stab bars were on the 88 caprice broughams?

Any auto parts store should sell both the poly bushings and the rubber bushings. The poly ones last longer, but tend to make for a slightly rougher ride as the rubber don't last quite as long, but give more cusion and a smoother ride
