I took off the widow-maker rims and got some splits (2 piece) that had the same offset. I know about bump-steer and i want no part of it,,, especially with manual steering.
You're right about those old white spoke rims. Too much positive offset.
I've built other trucks with straight axles.
The spring eyes are the attachment point. The spring center is the lowest point. What I've seen happen is; the center whips left and right. The chevy springs are slipper type with only one bushing,,, and no shackle. That one bushing just isn't enough when the truck is raised (NAPCO blocks). Also, the springs are pretty narrow for the weight of the truck. Later stuff has wider springs and the U-bolts get a better grip.
I'm changing the U-bolts today.
