Does anyone know of a resource for replacement parts for my specialty front door. The knob is located in the center of the door with a bird theme metal plate surrounding the knob - door is 35 7/8 wide - I would like to replace the knob - the hardware still works fine, I just need a compatible knob. Also, interested in replacing the decorative plate around the knob - Any leads would be greatly appreciated. Thanks, Alissa in Portland
