Questions on measurement
When you measure the spacing of the rear dropouts, to you measure on the inside of the dropouts, the outside, or the middle? Does it really matter?

I took a few measurements and got this:
124.7648
123.5456
124.2314
124.6886
As the size for the dropouts. What size hub does this correspond to?

In any case, I think a visit to Uncle Sheldon is in order. Here is a link to get you started

your frame is spaced for a 6- or 7-speed hub.

I guess I was looking more for a hub width in mm. The ones that I see are either 120mm or 126mm. Which of those sized would fit my bike best?

126mm will fit. If your frame is steel, then you should be able to stretch it open abit and slide a 130mm hub in there. If the rear triangle is aluminum don't try this option, just get a 126 and it will be fine.

Freewheel hubs can also be spaced to fit your frame, but keep in mind that probably means trimming the axle down and may limit your to a 5-speed freewheel or an ultra 6. 124 +/- 1mm is so close to 126 you might as well not even worry about it.
