Ford 1950 ring and pinion?

[Ross F-1]

What rear end do the cars use? Just recently 3.54 gearsets for the 48-50 trucks that use the Dana 41 have become available. All said and done it's not a cheap alternative, unless you can set up the gears yourself, but it may be cheaper than finding an OD trans and all the bits and pieces. Of course, a good used modern axle is even cheaper.
