IOwnA2001Echo2Door

Hey everyone, im having trouble finding much real evidence to support this but it seems that the rear suspension setups from all echo's and even the early yaris (1st and 2nd gen) look completely identical from a glance but the yaris seems lower. I wanna lose some of the height in the rear and I wanted to know if anyone has done a swap from yaris springs and shocks onto an echo? Any knowledge on this would be really appreciated. Thanks!
