Chassis modifications started with cutting out the round tube crossmember and replaced it with 2 x 1" rectangular tube. Bolting thru the original Ford engine mounts and towers tied the chassis rails together to retain strength. The new crossmember incorporates steering rack mounts and a vertical gusset up to the new strut tower. Reworked oil pan to clear the steering rack.
WTF are those strut towers u ask? I'm old enough to remember those squeaky horrible Falcon front suspensions, and wasn't going to endure that in my own car, so in went GM Holden Commodore V8 struts, PBR 'Corvette' calipers and rotors, lower control arms, master cylinder and booster, steering column brace (that's what the brake/clutch pedal bracket is really called) along with collapsible steering column and power rack........ALL UNMODIFIED. The caster rods are Commodore, straightened slightly at the front and mounted thru the original Ford chassis brackets using Ford rubber donuts.
Over here we have strict engineering certification to be met before registration, and using those components unmodified is the best way to gain certification as they are ADR'd for series production(Australian Design Rules). This project has sailed thru....just got to do a laptop braking efficiency test asap.
You guys know a Commodore as Chevy SS or G8.
Engine bay braces and Export brace are 0.75x 0.65" 4130 tube with 7/16" rod ends. Note that it's a perfect triangle....I'm yet to see another. Firewall bracket spreads the load across most of the width of the engine bay. There are 1" square tube diagonal braces in the shotgun area from strut top to firewall.
The original Ford torque boxes were trashed as usual, so I digitized the floor side-to-side and lasercut a full width top hat section incorporating a propshaft safety loop. Gearbox crossmember same story.
Exhaust is currently 2.25 two into one but it's too quiet and will be reworked eventually.
