This is a new design that matches the original plates. Orders shipped after 9/5/2015 will have the newer design.
These are not needed on the Yugo's unless you aren't using the original pistol grip mounting plate. This plate welds to the rear lower section of the receiver to strengthen that area when using folding stocks. As shown it is set-up for an underfolder. The bend is in the right spot and not touching the hole so there are not fitting issues.
