Sway Bars - what fits, what doesn't?

[Jon01]

Apparently my 71 doesn't have either a front or rear bar.
This makes for some interesting driving dynamics at highway speeds

I was leaning towards the CPP f/r setup as it's inexpensive and looks like it would work well.
However I've read of people having interference issues on lowered trucks, especially when they run a rack conversion which I could see doing in the future.
I don't plan on doing anything drastic with mine beyond the 5.5/6 drop I have in the garage for it but I sure don't want to be stuck with parts that don't fit.

So, what are you guys running on your rides for sway bars and how happy are you with the fit/function?
