Hi, have a question on the types of oem sway bars used for the advance design years. I have two types, one bolts to the front axle using the original springs u-bolts, replacing the spring bumper with one that is part of the sway bar. The other bolts to the axle just inside the springs using about 5/16 inch u-bolts. One is late and the other is early. Changed around 51. Which one is the late one???
Thanks
