I just looked and I don’t have any photos, but can get some in daylight tomorrow...I just used the factory mounting points to mount the bumper I built. Now it is not a “winch” bumper. But what I do have is brackets mounted to the bumper for my tow bar, and I have used that several times to drag the Zuk around with no adverse issues yet. Now I am not super thrilled with just the 4 little factory bolts, and so I am looking at some other options for additional mounting and strength.
What style of bumper did you purchase? That will definitely effect what you use for mounting.
