Discussed in past posts ad nauseum, but answer not really nailed. "as high as the jack will go is the usual response"..but.... I'd like to get this right on before dropping the sub-frame; but no higher than necessary so stuff is easier to reach. Shonut video says height must be 20" to clear transmission, but omits a critical detail; where this is measured. Does anyone have a measurement that will ensure the needed clearance?
