Original 1965 427 Cobra street roadster shock absorber info needed

[427street]

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.

Cheers
Greg
