New leaf spring bushings

[Customdeluxe85]

I ordered bushing and shackle kit from ORD. My old shackles are bent a little and the front hanger mount face on the outside is slightly bent in. After correcting the bent stuff, what's the best method to hanging the leaf springs back up while making sure nothing is binding and that the axle to spring position isn't twisted or offset? Or is there no such thing? Thanks.
