[Tiara Sovran] 4400 Sovran Air Conditioning Vent Grills in HELM area.

[Feetwet]

I need to replace the AC Vent Grills in the helm air conditioner outlets. There are four of them in my 4400 sovran and two have pieces broken off and close randomly.  Has anyone else done this and can anyone confirm this is the correct replacement?  

I would certainly like to order the correct ones and not have to return them.  The below links are for dometic products.
