Hello JKE,
Unfortunately I think your in for a long hard search for a spare part. Can I suggest that you try and locate precisely the same model rifle in full operating condition, get the owners permission to dismantle or remove the safety and then make a full engineering drawing of it including all cuts, angles and dimensions, then you find a gunsmith or skilled machinist to make you that part, if you can't make it yourself. It may be the quickest way of doing it.
Harry
