Not an expert by any means, but remember back in the day when consoles were plentiful in the boneyards that the one on the right (less bend) was more common on A and C bodies. I surmised at the time the increased shifter bend for the B body consoles may have been due to the proximity of the dash.

70 partsbook shows 2 part numbers for auto console shift levers, one for B bodies, the other for A&C bodies.
