If you are in a hurry you can "make" them work. Lelo Dart is right, you can shim the drivers side reward lug if you want. Just snug up the forward two bolts and fill the gap in the rear until it's close and then tighten it down. The passenger side is only missing a hole. So if you have access to a drill press and a 1/2" drill bit you can drill out the 4th hole. Easiest way to be accurate is to clamp the bracket on it's side with the 2 holes facing up. Use the existing hole as a guide to locate the missing one on the opposite side. Of course you could measure, if you want…duh. The side holes are on 2" centers. Now you have the required 3 holes to mount the passenger side and you are working this weekend.
