Roof vent Cracked

You should be able to find a lid at any RV accessory store that sells that brand of roof vent.

Note: White plastic or nylon SUCKS as far as longevity exposed to UV in sunlight. Black works best. In horridly hot climates I avoid dark tinted transparent lids.

They want me to remove the cover and bring it in for a match. That looks like I need to remove the entire unit.
I Cant see where I even access the hinge pins without removing the crank hardware. Then seal roof asgainst spring rains, then wait...
