They sell the woodgrain two ways, one with the fratzog cut out which is the easy way... The other that they sell it is as a full decal... On that one you grind off the swaged metal on the back of the insert leaving the two pins... Replace the woodgrain & reattach the fratzog using your choice of techniques... I've seen them glued... I've seen the two pins drilled & tapped with a #2 tap.. & I've seen guys try to solder onto the pins.... I think the screws at the best method...
