KYB 743019 AGX for the 82-02 Camaro is adjustable and works.
By the looks of it, the T3 coilovers are also built around this shock absorber.
Someone correct me if I'm wrong.
I do have info, but I'll ask him if he's willing to hop on the realm and make a build thread. I know he's posting stuff on Instagram @datsim_labelle but I never really checked it out.
