Hi Jerry,
Thanks for posting this issue. I've got at least half a dozen projects on hold due to not being able to replicate the front wings And my scratchbuilding attempts have been woeful
Not seen any aftermarket kits to modify this area and the only modern (post 2005) Top Fuellers I've seen modified were by Clay Kemp on another forum.
If you want to see pics of 2 of his builds to give you some ideas, check out

The first pics on both pages are of the front wing area.
Hope this helps and best of luck with your build.
Andy.
