No hassle headers for 66 dart w/360?

no one has mentioned the hedman 78500 with the #1 tube modification , saw it on a 65 cuda 360 4 speed , owner said they where a pcs of cake , alot of clearance even for the z bar with stock suspension . there shoukd be some pics if you research it ,, while we are taling about header ... there is also [ still aaible factory direct] for 650 the hedman fenderwell 75110 for the 63-66 a bodies , this was comfirmed by my email from them they will still make them for you like i said 650 FROM THEM ONLY my question after seeing this headache for years while builing my 66 is , i would order the 75110 , does anyone know , or have run them , the pics look like [since they turn 90 degrees] and fit up under the floor pan ,, they look as if they are inboard more than the hookers ? SO does ANYONE knowif they interfere with the turning radi and not with the t bars turned up all the way ,,with 13s as some of the cheaper ones did ? these 2 options are all i can find that will work for me , but like you all , im noe spending , till i know that they will clear the steering ,, HELP !! somebody had to run these a some time , saw alot of pics and info BUT ?
