What are you talking about
How wide is the van, how wide is the roof top?
I looked at the picture again
I like i said different wave lengths
Your trying to put the new vent inside structures inside the existing hole
That is only going to work if the existing hole. Is 14"
If you have to enlarge the opening
It's not just the fiberglass you cut
You have to cut everything
You need a 14 " hole all the way thru the coroplast ceiling
Or you won't have access Space to the lifting knob, and inside trim
Go measure the box part of the vent that drops thru roof
You will see what I'm talking about
