Another Torsion Bar Question

Am rebuilding my 72 Imperial. One of the torsion bars is slightly bent. Does anyone know the specifications on 70-73 Imperial Torsion bars? I have measured 50" length, 1" dia., 1 3/8 hexes, but the clocking I have not been able to measure. I need to send this information to Firm feel to get a set made. (I can pull a set off my 73 parts car, but that starts the dismantling of that car! I am so busy with harvest and building a house, I really do not want to start that!)
