66 Barracuda Headers - Help!

I am looking for a set of those headers for my car. They were installed in the early 80 s and have rotted away HELP HELP , my headers though looked different at the collector. I had to modify a collector shorter with a 45 degree bend so the exhaust wasn t on the ground. Oh yeah I have a 64 dart 340 4 barrell with a 4 speed 391 gear Lots of fun!!!!
