Crap, this thread is perfect: my buddy has a HP 60 kingpin and 10.25 for sale $1200 and I was thinking about selling my built-ish Toy axles to buy the tons. I have 37s and didn't think about the whole "ground clearance" issue... duh.
Spend $1200 for axles, maybe $1600 for tires and $500 for wheels. F that!!!
Toyota axles for me; gotta get Longs someday.
