Wanted: 1969 Browning Buttplate Buttpad 3 Inch Centers

Looking for an early 1969 Browning BAR buttplate,  It's my understanding that all butt plates from rifles and shotguns of that era are interchangeable. 

I need one that is 4.65" x 1 3/4" and a hole spacing of 3"    

Picture is for attention only its not the correct one the screws will be closer to the browning font.
