Non tabbed drop outs have had various mods to handle a der mount that depends on a tab. A common method is to drill and thread in a small set screw into the hanger's perimeter at the same rotational location as a tab is. Then this screw sticking out acts as said tab. This is as old as the hills. The drop out in the photo would need some grinding away which will create a tab, also a time honored method. Andy
