The Ford Barn

My friend here in Scotland has got hold of a 1940 mercury coupe, it is missing a rear axle and torque tube.
Would a 1946/48 Ford torque tube / driveshaft be the right length?
I know the simple answer is try it and see, but he is 150 mile round trip from us and my cousin and I are trying to identify and assemble the right parts from assorted Ford rear ends we have before we make the trip.
Thanks in advance for advice.
Gordon.

If my memory serves me right, and I am not too sure of it these days, the 39-40 Mercury torque tube looks like it has about a 5-6 inch "spacer" near the center. Very obvious.

The Mercury pinion is an extension of the one-piece drive shaft.
You'll need the whole Mercury drive shaft and torque tube, otherwise there'll be some fabrication in your future...

I suggest the 46-8 is the same .I have a 39 Merc ,they are 116 wheel base same as 46 ford . The early merc. drive shafts were one piece but the latter and 40 were 2 piece same as 46. The early Merc. housings did use the 112 39 Ford tube with a piece welded in the centre to lengen them to 116. So what you have should work.
