Truck 07 and he's in the north so he's rusty. Removing the old shackles was a 12 hour nightmare. Punch, grinder, jackhammer, saw, cutter. Suffice to say, if you have an old truck that uses road salt and you don't have the tools or experience, you won't be able to do this installation. There's also a seam just above the spring pivot, and once lowered, it hits that seam and squeaks horribly. The instructions say to bend, be sure to bend. Then I had to bend down with a pneumatic hammer, thinking I was lucky. Like the new truck dock. It's worth it.
