The half ton springs will not fit.
I used the springs from a Toyota,they have to be cut off with a grinder or torch and welded back on.
2nd-a one ton frame is straight and the 3/4 has a hump over the rear end,this would be best if you don't want your axle to hit the frame.

If we choose being kind over being right,we will
be right every time.
Knowledge is a poor substitute for experience.
Remember what is precious to another, may not be to you, but it
is precious nonetheless.
