We would want to use the #1139-149 over the -146. Please keep in mind there is a side note for the #1139-149. This is what it states" This kit uses a flat plate that is held in place by the leaf spring U-bolts on the rear axle. Check to ensure there is enough exposed U-bolt below the nut to accommodate the factory nut and washer once our 1/2-inch thick plate is installed above them. If you do not have enough exposed U-bolt, order one of our U-bolt replacement kits. For U-bolts with a square top, order kit 590050-00. For U-bolts with a round top, order kit 590050-10. We have the 590050-00 U-bolt kit available to sell. The 590050-10, unfortunately, is not something that we carry at this time.
