Tincup's 63 Dart w/5.7 Hemi
I have seen a conversion on a right hand driven car and the person that did it was able to do the same and mentioned that it actually worked out for him because he was able to have the space to keep the power steering and that the swap was a hole lot easier. I would first check to see if you could find out who the guy is and get info from his build.
By the way I like the Tranny crossmember but how would you attach it to the car.
