Mason’s Mean LS Powered Mustang 5….3?
Roll cage gusseting around halo and on A pillar
Here’s another close up of the extensive work that went into tying the roll cage all together and to the chassis.


Completely hacked up trunk lid and vents in rear panel
This was the back of a Ford Mustang. Now, it’s kind of hard to tell.

Remember that rear-mounted radiator setup we talked about? Well, this is a side effect of it. There’s very little Mustang left out back, as the trunk lid has been eviscerated and trimmed down to the bare bones. In addition, wire mesh vents have been installed to allow air to flow out the back. You can just make out the fuel filler and some of the radiator equipment.


Rear-mounted radiator with puller fans and fuel filler neck
The Dillon radiator is mounted in what used to be the trunk area, and the two massive 14″ Mishimoto radiator fans pull air through and send it out the back.

You can also see the fuel filler neck for the fuel cell, whose clear tube also doubles as a level gauge of sorts.

Josh completely gutted the bottom area of the trunk too, and fabricated this tube-frame cradle in its place.

The cradle holds the SFI-rated Jaz fuel cell, and you can also see the fuel filter sitting on top.


View under car of fuel cell, differential and sway bar
Mason spent a lot of time setting up the back half of the car.

A Whiteline rear antisway bar ties the two sides of the suspension together and, nestled carefully in the differential housing, is a simple spool. Just because it’s not fancy doesn’t mean it won’t work.


  1. Great build. Very efficient use of resources.

    I have shocks that extend into the engine bay and I had some tie rods with spherical bearing rod ends that I bolted to the top of the shocks which I triangulated to the firewall. For about 5lbs in weight the increase in steering precision is phenomenal. I have never seen anybody else do that mod but I swear to god it is the best upgrade I have ever done in terms of price. I had to carve out a divet with a angle grinder and reinforce the mounting points on the firewall. Great bang for buck, though.

  2. Swaybar endlinks tied to the rear bumper support? Am I missing something? Maybe it is just the angle of the pic on Pg7.

    Somebody please tell me I am wrong.

    1. The swaybar is mounted to the axle, and the ends are bolted to the chassis.
      Backwards from how it is on most cars, but the end result is the same.

      1. Ah, yes. Thank you. I thought the Mustang was multi-link now, but I must have missed the Chevy live axle part in the build description.
