My NAS Interspace armboard and my new to me Nima tonearm have been sent to NAS so they can see how best to fit a new armboard for me - or add to/adjust the current one. So this is a good chance to finally get around to fitting my Jelco 750 to my newly acquired (6 months ago ?) Garrard 401. I have an old SME type wooden plinth - lead lined. So I need to drill a new hole for the Jelco, I have a template, so the distance is fine, but I'm just wondering does the vertical placement matter? Obviously it will sit at somewhere around the top right hand corner, but how specific does it have to be? And how do I know exactly where to place it? Is it slightly above right hand corner? Or may'be right on the corner, or below?

You can see from pics that right on the corner the armboard would be a bit too close to the 401 to fit exactly at 229.
