A piece of gaffer / duct tape across the bridge of the top and metal frame will prevent air from catching the roof for the time being. If you do it ugly enough, you will be driven to have the top redone!

Wind noise - clear bra
 

Sounds different, but the PO of my '88 owns a firm that clear bras cars. He put a strip of clear bra material on the space between the windshield and the Targa top leaving a bit of extra hanging over the top. Makes it a bit more challenging to put the top on, but it cuts down on noise and water from the front of the Targa top. If interested, I will post a pic tommorrow.

Cheers,

Jeff

get a proper front seal, then adjust the windows for a proper fit using Gerry's pdf post.
