Here is something a lot of you guys using a 2005 and newer Ford F250/F350 Superduty and 2016+ Dodge Axle will appreciate. This bracket will mount to the factory radius arm locations for the upper and lower mounts on the axle end.
Since each bracket is separate for the uppers and lowers it will allow you to adjust pinion angle depending on the size of your lift. They are designed to use a 2" O.D. tube and are made from 1/4" thick plate. Sold as a pair so you will want to buy 2 sets to complete an axle. They come unassembled and do require welding.
