What spindles should I order?

[cdog73]

Was just wondering what you guys think are some of the better brands of spindles out there. I will be putting them on my 71 C10 with front disk breaks. Is there a reason some people run the 73-87 spindles on older trucks? Just wanting to get some ideas before I order, so i buy the right spindles the first time. Will be adding air ride also this year and then next year it will be Porterbuilt front and back. Not sure if my truck has the 1 " rotors or the 1.25" rotors if that matters.
