This is weird Mike ... I took my dometic out and put the Vitrifrigo in and gave the Dometic away. The only part I kept (no, I don't know why?) is the part you're looking for. Does it have 3 notches, equally space around the edge for the screws, with the 3/4" hole in the middle?
 
If so, send me your address.
