it will be very hard to do parallel on an s10 cause you wont have enough room to the ends of axle to be able to mount brackets to frame. on full size, this is possible cause stock leaf spring hangers are on side of frame, not below.
sounds like your triangle bars are too long. mounting them under axle will not work as you found. you also want to mount them sideways to the x-member, not on top or below, this wont let it pivot.
you might want to either get a wish bone for the 3rd link or just do one forward link on passenger side and add a pnahard bar like on devious customs 3 link. i've put that on before and it works good.
