Hi all, on my 1973 911S which is a crazy mix of parts (964 bumpers, turbo flares, etc), I recently noticed that the car came with aluminum trailing arms and funky torsion bar tube mounts.

Does anyone know if the torsion tube has been replaced or just the trailing arm mounts? Maybe this is a turbo or G50 torsion tube?

Note that it has the RS/SC reinforcements which were welded on. I also think the mounting point looks further out, making me think either Turbo or G50. But I'm not sure which and what the proper course of action is now for my restoration.Name:  IMG_1465.jpg
