I've got a 54 front end under mine. Everything bolts up. The actual part number for the 37 axle is not the same as the 41-55 1st, but the axles and the parts will change out. The same tie rod works on all of the front ends.You will have to maintain the 37-46 pitman arm. You can also up grade the steering box from 37 to a 41-46 and another smart thing to do is up grade the tierod ends. The main difference in the front ends is the axle size and the king pins. The 41-54 axle is heavier and the king pins larger. Both of these differences make the front end a better, stronger and more safe front end.
