What? They couldn't get Rick a Hawaiian print hospital gown?

Just a matter of time before that bed has Shelby wheels on it.

A hero in my boyhood. A hero in my adulthood.

A bloody fine chap.

May we live lives with as much dignity and humility.

Godspeed Sir Sterling.

The brake rotors appear to be available on the Tony Branda website.

What is the serial number and build date of the Hertz car you are working on?

From what you are saying I'm guessing you have the Boss 302 spindles and need the larger Boss 302 bearings/rotors.

Hi guys. The front rotor and bearing size on the 69 GT350's and GT500's were affected by a mid year (Feb 69) change from the regular Mustang front spindle to the Boss 302 front spindle.

Ford/Goodyear changed the tire size from an E70-15 to an F60-15 and the wider tire put more stress on the spindle bearings so the Shelby's changed mid year to the larger Boss 302 spindles.

The change was serial number and date dependent for both the Hertz cars and the Shelbys.

Hi all. Can anyone tell me the specs of the original 427 Cobra street roadster rear shock absorber and coil spring.

1) Shock absorber length (eye to eye) fully extended and fully compressed

2) Coil spring length, ID, OD and spring rate (lbs per inch)

Thanks for your help.

And a Happy Thanksgiving to all.

But if you lube it, do you use CASTER OIL or CASTOR OIL??

Cheers
Greg

OOPs.

CASTER!

Yup . CASTOR.

When Ford in 1964 used their first computer simulations to design the independent rear suspension on Shelby's 427 Cobra, they were actually able to design in some rear steering and anti squat when the rear suspension went into compression.

This aided in rear stability and straight tracking while under heavy straight line acceleration or accelerating out of turns where a bump might occur.

So at static (rest) or driving in a straight line with no acceleration or bump compression in the rear, the rear upright had a 2 deg negative CASTOR built into it (top of the upright leaning slightly forward).

Under hard acceleration or a bump (compression),  the Upper Control Arm and leading Lower Control Arm links were so designed (with anti dive and some rear steer) as to move the top of the upright rearward and into Positive CASTOR and created some additional toe in on the rear to aid in directional stability.

I think.

It's really a complex rear suspension.

Hi A-snake. I have now learned the CASTOR of the rear upright was spec'd at 2 degrees negative (the top of the upright slopes towards the front of the car).

Cheers
Greg

Can anyone tell me what the static Castor is in the rear suspension upright of the original Cobra 427 IRS.

Thanks for your help.
