I want to install a sunroof in my 91 Carat.

In that connection I would like to terminate the A/C tunnel and  housing
above the back bench seat/bed leaving the area over the front seats  for the
sunroof. I live in the pacific nw so A/C is not a must and I still will  have
enough flow to cool the van down.

My question is has anybody done or seen this type of modification.
