Rear suspension is my own 4-link. Lower arms were fabbed from 1.125" X .156 dom tubing and McMaster Carr 4130 hi angularity rod ends and their left/right threaded inserts. These are installed in the Ford leaf spring pickup points. The uppers are Jaguar IRS forged steel lateral (camber) links. A packaging bonus was that the curve in those links clears the standard rear axle crossmember at bump, thus achieving the best side view location for the upper pickup point without removing that crossmember. 4130 rod ends ride smooth and quiet so far.
AirRide 4" airbags on my own lasercut* axle brackets, with the top of the bag mounted against the original floor pan. A new fabbed crossmember above the floor takes the load of the airbag as well as top mount for the Monroe gas OEM shocks. Airbags allow me to raise the hitch to load my sprinter without highcentering on the trailer frame.
Panhard bar is a shortened Range Rover steering tie rod which already has a left/right threaded adjuster and swedged tie rod ends.

*I am ex-GM body group cad designer so lasercut designs are what I do to keep my sanity.

Battery is in the rh trunk dropoff, master fuses on the trunk floor, battery positive cable runs to drivers seat pan with Cutoff switch accessible at front of driver seat cushion. There are more fuse boxes under the driver seat. I decided to convert the Falcon to right hand drive because I have the time and also makes the car easier to sell eventually.
