its the latter, unequal lengths will keep the pinion angle and rear steer to a minimum. Just like upper and lower control arms are unequal length, equal length control arms will have MORE camber change, and it will be wacky camber too.

a good way to check this stuff out before even ordering bars is to scale model it with paper first. figure out how far apart (y axis) the bars will be at the front attachment and at the rear axle. then cut some paper strips and use round head fasteners (office supplies) and a hole punch to make an "axle" and "bars" and a "frame"

then you can use a pencil to trace the pinion angle at different heights.
