What is the shock length for Speedtech TA on a 69 camaro?

[CSG]

I am wanting to know both extended and compressed shock length for the SpeedTech torque arm on a 69 Camaro. I need to get my rear suspension but have not decided yet on what route for my front so I am wanting to see if I can use one of the sets of coil overs that I already have for the time being as obviously I may need a different spring setup once the front is determined.

10.04 compressed 14.24 extended 1/2 x 1.25 upper bearing mount 5/8 x 1.25 lower bearing mount

Thank you sir.
