Ol' Blue's magnum swap

What are those headers you are running? May try those on my magnum conversion in my 65 dart...
Sanderson DD9, But I'm warning you, convert to manual steering or you're going to have to bash the crap out of them! And then they still don't sit down all the way, I had to shim up my motor mounts which changed my pinion angle relationship heading to vibration that I'm still trying to get rid of. Either spring for the TTI headers, or convert to manual steering
