I did mine it was straight forward but I didnt have instructions. You can tell that they (brackets) are made for one side or the other. Also it very important to have the truck on all fours for weight position. Mount leaf brackets 1st softly, position bar to rail, get rail and axle brackets squared away , then tighten up axle brackets ,check position of bar and rail again, mark rail for rail bracket.let bar hang or tie up mount rail bracket install bar.Tighten
I think this is what I did.( the nuts in the brackets took a skinny socket , for some reason mine were difficult),
