Since I had bought the 1/2 ton mounts before I realized they would not fit... I went for the method that involved splicing the two mounts together.
It was a fairly simple process;
- I took a whiz wheel and cut off the far mounting hole on the purchased mount
- Put the original bracket on the u-bolt then put the not cut bracket on top of it, then I marked the location to cut on the original bracket
- Cut original bracket and grind so both cut faces contact cleanly/ grind "V" to help in welding
- Clamp to a flat surface and weld
- Grind away some material for clearance on the axle. (There is a raised portion that I don't think is on a 1/2 ton)
