Shown here is a 4 bar brackets I have designed to locate a 9inch diff with coil over shocks on the rear end of a lowered 1969 - 72 model F100. I use big rubber bushes oversize 4 bar tubes and utilise the leaf spring forward mounts to keep chassis modifications limited to the rear end notch for diff clearance. I will post some more pics of the finished set up soon, it has worked a treat. Kustom Bitz can custom make 4 bars to suit any application. All custom work is done at an hourly rate.
