Merc 1939 axle in a 32 frame need help with torque tube lenght

[Seth Swoboda]

What's the advantage of a '39 rearend in the '32? Seems like a lot of work for a result that makes you go down the road all the same?

Much stronger rear axle, hydraulic brakes.

Not trying to be an antagonist or smart donkey here BUT I am STILL trying to figure out......"IF" he already "have a complete 39 Mercury axle", why did he need the torque tube measurement, couldn't he just measure the rear end he has???? BUT what do I know???

[Cheaterpete]

the 39 axle center section is not the same size, the swap is not bolt on and the torque tube on the 39 is way longer ths need to be reduced.

I "think"??? Through 41. I have the torque tube and shaft and ring gear I picked up out of a 40 Mercury that is one piece.....SO at least through 40.

I have been searching to find the stock or common axle ratio for a 1939 Mercury with little success. The one I have is 410 but would rather 378 if it was available and if I can find one. I could change to the normal short pinion and modify the driveshaft to use a coupling but that is a daunting task. Any thought or suggestions would be appreciated. Thanks, Bruce

Pete, you can avoid the hassle and put a late '32 rear axle in your car. I have one available for sale, if you're interested. P.M. for details.

I have a '39 Merc Town Car and its ratio is 3.54. I have a Columbia rear end built with a 3.78 gear set that came from a 1940 Mercury. Hope this helps.
