Finally remembered that I already acquired new Sensenich prop bolts & washers, and mounted the used FP prop. The used prop already had both spinner mounting plates, so it was easy to test fit the spinner on them,
This is a very preliminary rough test fit of the top cowl, to get a quick view of the components and approximate positions. Nothing looks way out of alignment, and it's a good 1st look. Next will have to mount a bracket on the nose gear mount, and test fit the bottom cowl.
There is not intention of marking, cutting, or measuring at this time. No glaring problems.
