429 headers in a 66

[fordsforme]

ok so my car is a 66 and it has a 69 thunderjet 429 engine that was installed 18 years ago. now there is nothing wrong with the manifolds im just wanting to open it up a little and soon install a big cam.the engine was rebuilt and bored 40 over before it was installed in the car 18 yrs ago by the previous owner he said that he had only driven it around 2,500 miles or so because of a rusty fuel tank and then he parked it which didn't help it now the most of the lights aren't working and now i have it >yea. i can't find anyone that makes headers for this car engine combo.there are mock up do it yourself kits i have found that range from $500 to $1,700 but im not confident enough to build them myself alot of money wasted if i screwed up so im really im just looking for a bolt on . they make them for the 390 and 428 as the engines were offered in the car but lucky me the 429 was not. i have contacted a dozen of the major header makers and they can't help anyone no where i can find some bolt on headers or no if they even make them.thanks
