Hello,
I have sort of the inverse problem solved by the JX961A - APs with the new style rail-mounts pre-attached (AP5xx) but I'm looking for an adapter system so I can use them with mounting brackets I already have attached to suspended ceiling rails and also to 4 post mounts, both attaching to the older AP style with the twist-tab system (which uses the old style pictured.)
The new mounts really present a labor nightmare that I'm hoping to avoid.Thanks to all the spatial-visualizers out there who may be able to help.
