There were two shapes listed, one with a distinct bend, the other a smooth curve for B and V8...can't remember without going home and looking which is which. I have examples of about 4 different shapes...all begin and end at same geometry, so no sweat. There were also early ones with 2 top holes, the extra for the power clutch that never made production!
I'd suggest slightly bending out a common later short one, then welding on a fabricated arm to '32 length welded the full length of the short one for extra support.
I think I can find a loose real one you can use as a model.
