It's the space between the dropouts that you need to measure. That is to say, the inside width. A vernier caliper is by far the best tool, but you should be able to do it with a ruler. Not to put to fine a point on it, but your measurement skills are terrible. Work on it. You need accuracy to 1/32" at least, not 'around' 1/4" or whatever. Better to buy or borrow a better measuring device and measure in mm. If you aren't comfortable with it, take it to a bike shop and pay them to do it. Oh, and take the wheels off before you measure.

It's almost certainly 100mm in front (standard) and 135mm in back. However 1994 was a transitional time, and there is a very slight chance the rear hub is 130mm. (they made both 130 and 135)

So, if you buy from velomine, most in that size would be listed under 29'er wheels. (mountain bike 700c) Problem is these are mostly sold to MTB'ers, and these days that means disc brake hubs. You want regular quick release hubs. Rims will be a bit on the heavy side, but that's ok for touring.

Velomine's website is kind of screwed up right now, you might have to do a search and or email them. Or try Amazon, etc, one of the vendors that sells through amazon drop ships wheels from Velomine.
