Spring Relocation Question

there are 2 ways to do it,

1st use has offset front hangers that move the spring in 3/4", and use a 3/4" offset shackle in the rear...
Here are the basics...

2nd "The Kit" moves the rear shackle through the frame(like you have seen), and the you cut/weld a new box into the frame up front that the spring sits between also. Looks like this...
