I installed mine with the car sitting right on the ground. If you remove the front leaf spring bolt from the bucket (so to speak) it won't hurt a thing as the weight of the car keeps everything in place. Then you simply slip the frame connector into the opening of the front sub frame and then I put a floor jack under the frame connector to force it up into the leaf spring bucket/pocket and put the bolt back in. Then drill the holes through the sub frame and push the bolts through. The ones I bought also came with tubes that went inside the frame connector to keep it from collapsing from the force of the bolts...
