Reed 3P armboard mounting

This is question is steeped in ignorance. Does anyone have experience mounting a Reed or similar tonearm to a wood armboard? The 3P seems to use three M5 screws. I would guess the most reasonable approach is installing threaded inserts into the armboard, although that creates more variability in getting an accurate P2S distance. In contrast my current tonearm is attached with a threaded post clamped the armboard with an underside nut. There is enough side-to-side shuffle in this arrangement to get a very accurate P2S. Thank you.
