Save yourself the expense, weight, and room. A TKO 600 will fit very nicely and they are rated for 600 lb-ft of torque. They are available in either a .82 OD or a .64 OD, so there's really no need for a T-56. I think I've sold one Magnum T-56....to a customer that insisted. The TKO's can be modified to hold as much torque for about the same money if torque capability is needed. Otherwise, it's good to save the extra weight, girth, length, etc.
