How hard is it to set the rear springs outboard of the frame rails? All it looks like you have to do is weld box tubing to the outside of the frame and mount everything to that, and since I'll be using a buggy spring mounting the rear shackle will be a snap. But what about the front spring hangers, where can I get those? What else will need to be modified? E-Brake, longer break lines, etc??? Thanks in advance.
