Dropped Spindles...(best and most economical)

[slammd72]

i was wondering what the best and most economical dropped spindle was. i need to get mine quick, ive got the sd plate and cup set on the way and i need to get the front of my cc dually on the ground and half ton. let me know. also whats with the two different spindles from jeg's one is for 1.25" thick rotors and the other is for 1" thick rotors. im going to be purchasing brand new rotors for my half ton conversion so do i need to get these first? and then measure the rotors before i order the spindles?
