70 dart swinger slant turbo build and mild restoration

I have his blue print to build those I might just see if I can do it but can they be ran with power steering and ac? They are a super easy and cool idea but I think the room they take up might be an issue? Also I don't think u have to weld mild steel to cast because the j pile is all self contained just run a brace to hold the turbo. The headers I'm building are thick enough you won't need that brace there schedule 40 pipe about the equivilent of .120 wall tube
