Need header advice on my 71 Dart

I've been looking for some headers to go with the new 360 I'm building. I like the look of the fenderwell headers but I can't seem to find any place that sells them.
have fenderwell headers gone the way of the dinosaur?

If they truly are not making them anymore what other choices should I look at?

If you have picks of your headers that would be awesome.
Also a short description of how hard the install was, a six pack or are we talkin a keg to get it done?


Thanks for the help.
