I bought one of the early Particle Wave Monolith piers, and it had a full index adapter for an AP1200, but couldn't be drilled or modified for a 900 due to how it was ribbed and relieved underneath.
PWT is not making adapters anymore so I had been searching for a solution.
I discovered the 1612FSA-FP from AP which is designed for a 10" ATS pier. Turns out it fits the 10" Monolith perfectly (remove cap screws from circumference of adapter and use Monolith internal clamps.)
Also it is drilled and tapped for both the 900FSA and the 1612FSA, which then accept their respective pier adapters.
I realize this is right up there in the minutiae zone, but it is a great option if you come across a Monolith pier without an AP full index adapter.
