Sucks that the springs got beat during shipment, that shouldn't have happened. Shame on the shipper for not packing them better. Nothing like adding a little unnecessary frustration to the mix but at least it appears you're back on track.
I had a similar occurrence installing a Thuren rear leaf add a pack back in 2006 on a 3500 Mega Cab and the center bolt didn't line up right. Seems like things don't always go smoothly and **** happens which is par for the course.
Still better doing it yourself and knowing it's correct even though it can be a PITA!!
Nice work, it's gonna be awesome when all said and done
