i agree, without the connection to the trans it would probably twist right off, i think 25 deg would be a conservative estamate. i'm doing a 64 now and the third member has a bracket that bolts to the housing directly under the pinion but bolts to the frame with rubber hockey puck bushings above and below the frame bracket so they are not really rigid either.
