I was the one who tried it in that post. With some longer shackles, this swap would most definetly work. I just stumbled upon a cheap set of lift springs, so instead of fooling around with shackle lengths, I opted to go the easy way out. I may come back to this some day, but I will make some drop hangers and shackles to accomodate. To put a stock set on, you need to grind the superduty bushings down, drill out the the hanger, and make a longer set of shackles (how long I don't know, but at least 3" longer I would guess maybe more).
