We had a Rancho suspension IFS lift on our 1st gen. The kit consisted of all new Upper A arms with mounting brackets. Had a new frame member (bolt in) in front to lower front differential. Had two brackets to carry the front differential lower. and a stiffening bracket (in black) below the front diff in back and it bolted to the inside of the frame carriers of the LCA's. Will try and post some pics.
Most of the parts are Red. UCA
Lower bracket
Can see red diff carrier brackets and gusset bracket
You can see how the UCA carring bracket wraps over the top of frame rail and extended down on inside of frame rail in this pic
