That is very true. We pulled an homologation Charger E38 out of a container in 2003 in Toowoomba still fitted with a half roll-cage and racing harness that had been fitted from new. (Car now in NZ awaiting restoration). It looked liked scaffolding tube and was clamped together. The car had been prepared by Jim Bayliss in Newcastle (Jay Bee Clubmans). I have also seen a few of the other privateer cars of that period fitted with this type of half cage.
