Maybe i am missing something... wouldn't be the first time.

Once the first bolt is through the prop, through the spinner backplate and started into the engine hub all the others should be lined up.
Yeah, I think you missed the issue I'm describing, or I'm not explaining it right,
see picture of the spinner type the OP is referring to.

Each prop must be drilled to aligned with the spinner slots and the back plate at the same time so it fits the slots. The only way to do that is how I described earlier or make a jig that will drill each prop to match the spinner back plate. The OEM drill jig in itself doesn't achieve that, those just align the 4 or 6 holes.
