Willys 38-41 axles differences??

Is there a difference in 1938-41 Willys car and pickup front beam axles?

I am looking for one for a car, and was wondering about possible differences in kingpin width, spring mount centerlines, shape, thickness, etc??
Any help with the difference (if any) would be appreciated.

 

None that I have seen, just hubs, brakes were different.

 

What he said...
Have seen some difference in the tie rod ends, but doesn't seem to effect the axle placement, and use.

37-38 have 1" more drop than the 39-42, The 37-38 use a dog-legged tie rod end for spring clearence. Also there are 2 different in the shock mounts.

 

37&38 axles have more drop. Thats why they have a drop in the tierod end. Its obvious if you lay them side by side.

 

Thanks, gents. I appreciate it.

Any more information will be welcome.
