Leaf spring bushings????

[backyardbuilt]

I sent My wife to the truck place to get my new energy suspension bushings. And they asked her 10 questions about the springs the shackle and the Tonage of the truck (1/2,3/4,1 ton) I have a 1/2 ton 79 blazer What do I really need to know I told her 1 1/2 for the bushings why would she need to know about the shackle do you get those to do you know what the part # is so I can save there 20 questions had to send her I've been working 12 hour days and there closed when I'm home. Thanks for any help!!!

Look at Summit's website. They're all the same for the 1.5" springs to my knowledge. If you have to, look up the part number on Summit's website and then have your significant other go to the parts store.
