For what its worth I have known the one here in my town since I was a teen (Actually one of the sets of headers I have came off it) and it was always sitting pretty perky in the ass end.
The thing went through the regular phase of mods and racing after it was new and then the guy put it back all stock . I am betting its spent the majority of its life sitting in the garage now.

Falcon , do you mean like these ?  https://drive.google.com/file/d/1843nix0n9wnv7gbBq838XUTNL5OcfuZM/view?usp=sharing  ?? Yeah that doesnt solve it and yes thats the car I am doing now . WHen you turn in either direction the tire rod pushes harder into the tube and would have to lift the spindle and wheel to actually turn. Hard to explain unless you lived it. Its not just hitting by a small amount and removing the sleeves would solve it. I ran similar sleeves on the car I had the motor in before.

Brunson , thanks for that but I am wondering if they didnt have some thin rails from rust inside or something. They bolt through the rail so it would have to be comprimised for that to happen , but I will absolutely look when this thing gets going.

machoneman , well its like this. THe front end of these old things need some travel to transfer weight . You cant set it low enough and then limit it because the tubes will plow ditches in the road . If you limit it from a decent ride height its about to hit the tubes.

These thigns have been used for years , even I did it for many years , I get it. I just dont want to deal with it anymore and if I am starting over I am going to do away with the things I disliked.

Thanks Paulie !!! Do you have any pics of them on the car ?

Im not new to the forum but have certainly been inactive for many years . Getting back into this has been interesting to say the least.
One of the areas that seems to have very scattered information is Headers .

I am putting together my 70R code Mach and I have opted for the Borgenson steering box on it (Always hated the ford system).
Has anyone on here done this with a set of headers with 2" primary's ?

The set of Dougs headers I have seems close but they of course are plagued with other issues such as auto pilot when the front wheels are hanging after launch . I saw a set of Crites headers on a mustang that was on Ebay but the pics were limited. I did notice however that they put a dip in the tubes near the drag link to keep the tie rods from falling out on them under acceleration.

So who makes the perfect 2" header for 428 mustangs that actually fit the car and perhaps clear a borgenson steering box ?
