Believe what you want to believe, but it doesn’t matter if you have an MP kit or a home made hanger, there isn’t 3/4” of space to move the hanger.
The MP hangers on my car in the picture above are in contact with the frame rail, and required a hole and a dimple in the frame rail to clear the nut on the outside of the hanger. Unless you sectioned the hanger into the frame rail, there’s no more room on your car and the springs only moved a 1/2”.
Just take a measurement from the frame to the spring. In order to have a 3/4” offset at the front hanger there would have to be only a 1/4” from the spring to the frame. The spring eye bushing is a 1/4” thick there, so, that would mean the bushing would have to be flush against the frame rail.
