odd rear setup question...

ok so first of all my truck is gonna be bodied, but i also want to set it up to 3 wheel and maybe 3 wheel standing even tho i know its difficult to do on air...but heres my question...ive seen a few pics of someone buildin 4 links a lil different than most and i would like some input on it...the lower bars are mounted wide on the axel and angle towards the center and the upper bars are mounted narrow on the axel angled out towards the frame rails...arent you typically supposed to have 2 bars parallel to the frame? i know some of u guys on here are gurus when it comes to stuff like this so aome input would help...o and by the way im asking about this particualr setup because ive seen it 3 wheel but if u guys have other ways let me know....here are some links
