3" Vent Options

NRath

The 4 plastic vents in my Captiva have come to their end.  2 are connected to vent hose, and 2 are open to the engine compartment.  Plastic is ok, but I'd prefer something a little better.  They are surface mount outside the hill with about a  3" hole thru the hull.  They're tucked under the edge of the sun pad.  
I found these:

They look great and should hold up, but they don't have anything to hook the hose to.  

Seadog has these 90's that I believe would work with the vents:

But, I really need a straight connector.  Does anyone know of a similar vent or a way to use these seadog vents? 

Thanks in advance!

This is the vent on the defender site , made by Seadog:

Seadog says the 90 won't work with this vent and only had plastic vents with the "barb".

You could get a plastic collar and epoxy it to the stainless

That's a thought.  I've been considering tig'ing a collar to it, but worried it's going to discolor, though I could probaby buff it out.  In either case, I figure this has to be common and something has to be in the market to save me piecing it together.

Found this one with stainless over plastic, but not sure it'll cover the screw holes in the hull.  Nice looking vent if i didn't have 2 screw holes at each:

I used that exact vent and I used 4200 to secure it the the fiberglass
