I used what I believe are the same ones (ebay). They are a pretty bad fit with power steering. I had to file the flanges flat. I had to clearance heavily around the power steering box and steering coupler. I had to clearance around the torsion bars when I upgraded to 1.03. Even my idler arm was rubbing. The passenger side is pointed down instead of straight back. There are some pictures on my thread. 1968 Dart 270 NON-build
I think most who've ised the style are aware of fitment issues with power steering and such. My question is are they actually stainless steel? will a magnet stick to them?
