Have you figured how to bolt it to a slant? How would the torque converter attach to the flexplate? Rear mount? Need to cut tranny tunnel? Even a Magnum tranny in an A-body requires cutting the tunnel.
No, I have not done this personally. However, I am sure that an adapter plate would be easy enough. I need to research this but I have good information that the NAG-1 MAY bolt on. Please, dont hold me to this. I need to find out more.
The NAG- is pretty big compared to early MoPAr automatics. I am sure there would have to be some surgery to the floorpan.
