Have you looked at LCA's from the 73/74 B bodies? They mount the lower ball joint in the LCA directly and have a steering arm with no ball joint. The steering arm doesn't help you but the LCA might. Either way you'll still need something to hold the ball joint to the knuckle

But again, I'm not talking about welding on the stock steering arm. I'm suggesting that you should bolt your fabricated steering arm to the knuckles, because the way you're going to weld those arms to the knuckle will not be as strong. The rest of the construction isn't what I'm talking about either, the weakest point of this entire arm is right here at the red line, where you have designed in a hinge point with a large lever.

No, I get that. I'm saying you don't need to weld the fabricated steering arm to the spindle, because nothing changes for the rod end. You're still fabricating the steering arm, you just bolt it to the spindle because that will be a stronger arrangement
Hey if strength and bearing size aren't a concern for you then have at it. Personally I can't see racing one of these cars so competitively that a few ounces on the knuckles would be worth the loss of strength, but that's just my opinion. A knuckle failure at speed would be catastrophic
