The PBB FAQ is great, but let's go ahead and hit some high points.

You CAN move the front hangers, but it's a heck of a lot easier to get some from BudBuilt. They get mounted 11 inches forward of the stockers.

Stock u-bolts will work, but while you have it apart it's a good time to go ahead and do a u bolt flip. But that means you have to deal with a new lower shock mount. No biggie...

I did not move my shackle hanger. I use a single 9" eye-to-eye shackle in the stock hanger.

It's a great mod. Love mine.

If Mad Max had a 4runner...
