A modified 37-41 round back.

No, not '37. That was forged for the through-bolt type arms. Early A were round...do you have any '37 up ones to compare? If A, the spindle shaft will be a little less than 1/2" longer than the late V8. '48 up truck also used the bolt-through steering arms but these don't look right for those.

On that...check diameter of kingpin.

 

Bruce is right, I'm wrong. I should have known that as I have a pair of the early 28 A round spindles.

 

I'll check tomorrow
