The torque tube shouldn't be much different than that figure. I thing the 42 & later Ford cars TQ tubes were 71 7/8". If that's the case then the Mercury would be longer. It would be interesting to know the actual figure though.

I believe the 112 inch wheel base Ford car torque tubes for the 38 thru 40 cars were 69 15/16". The 35 thru 37 cars should be close to that too since they had the same basic frame design. Only the motor mounts were different for the 35 & 36 cars before the block mounted pumps came out in 37. The dimensions from the engine to the rear axle should be pretty close.
