This is just like our Rear Axle Simple Swaps with a few exceptions. First off you only need 3 Ubolts and 1 of them needs to be 3 7/8". Secondly, the cast in place perch has a unique pattern so we give you the unique pattern Ubolt plate and the standard Ubolt plate for the tube side. Lastly, you only need 1 Spring Perch so you get that too. It comes with our Curved Shock Brackets rather than the shorter ones so that you can ride up the C better too. The Cast Side Ubolt Plate is 1/2" thick to make up for the lack of bends.  These also fit some Dodge D60 axles, call us when you are near your axle and we can check if it fits yours.
