My truck already has 2/4 drop as the previous owner claim on rear it has shackles and hangers do I need the stock ones to do the flip on the rear? If stock is needed which one will work the shackles or the hangers? The hangers it has right now looks weird like they were made in home garage

 

You will want to put the stock shackles and hangers back on before you flip the rear.

 

Where can I find the stock ones? The junkyard in my country doesnt have any trucks but I can get them out from Suburban 90s will they work? I hope so

 

Not sure if the 90's era setup is the same as the 03-06. I would see if you can get a comparison or see if someone else may chime in.

 

It seems the hanger has been modified because I see another hole below where the leaf is currently fitted I will try to fit the leaf in that hole and see if it sits higher
