Late A Body fenderwell headers

Did anyone ever make a set of late A body (67-76) small block fenderwell headers? I would really like to find a set. Or has anyone modified a set of chevy headers to work? Just wondering what I can do outside of having a custom set made. If you are wondering why I want a set, 1 I really like the look of them, 2 I want to connect directly to my side pipes on my duster.
