There's a point near the top mounts of the oil cooler where the frame bolts together - that's your top mounting. The engine bars mount to the inner side of the frame hangers which requires dislodging the oil cooler slightly. The bottom mount point is the lower front engine mounting bolt, but you're supposed to be supplied with a bolt that's approx 1" longer than standard to fit the bars to. I wouldn't try it with the standard one as it wouldn't be long enough to provide a strong engine mount point and mount the bars securely.
