Regarding Durock / Zeal / 3rd party stabilizers: most 3rd party stabilizers should fit fine on the aluminum/pc/brass plates. However, there is a tolerance issue on certain brands such as Durock. Aluminum and PC will fit fine, but require some force. For brass, you must file off a bit from the side stab housing for them to fit. We are of course looking into solutions to make these stabs fit better for future batches as well.
