is there a difference between standard rear wishbones and cossie ones?

when i bought my running gear,i got it all as a package (front/rear axles,engine and box)

i have been removing the rear wishbone bush`s to replace as a little worn,i removed rubber pressed in bush`s.there seems to be a lot of mention about the cossie having a rose joint as such,have i bought standard stuff?

has anyone got a picture of here rear wishbones?

cheers
