And on a related note, are the early 90's 105 triple components relatively rare? I did some searching and I am not finding much of anything. I can find lots of octalink triple cranksets, but not many square spindle triple cranksets. And the ones I have found are not 170mm.

Yeah, the early 105 and RX100 triple cranks and triple-capable derailleurs are pretty rare. I took a while for "low-geared" road bikes to take hold in the marketplace... or maybe we all got old and slow. I forget.
I have a bike with an early 105 triple rear, 180mm XT cranks with larger chainrings, and bar-end shifters:

It's pretty neat, but I hardly ride it. Too many bikes!
