As seen on Tony Angelo’s Stay Tuned 600HP Turbo Lincoln Mark VIII build. This custom Powershift Factory rear differential mount & bushing is designed to work on any MN12 or FN10 rear IRS.
 
The chassis side mount is made from 6061 CNC machined aluminum and includes off-the shelf polyurethane bushings and stiff UHMW plastic bushings.  The two-piece side plates are made from steel to take all the punishment you can throw at them and will bolt up to any factory style differential cover like the Ford Racing Differential Cover or the LPW Differential Covers
