I have an '82.
I switched from 27 inch to 700c a while back. It looks like the stays were spread to 126mm by the previous owner.
I had no issues doing the wheel conversion. I will note the 40 spoke rear wheel is strong, but heavy. However, I have no doubt that the wheel will last a long time! The bike goes well with brown and silver accents, much like mine. Only downside is the lack of braze-ons, which ultimately may affect the value.

Touring bikes of this era are kind of funny. 27" wheels were already an anachronism, as was 120 5 speed. Yet the big manufacturers kept those features on their flagship touring bikes, for the most part. The thinking was when out on the road, you'd be able to get a spare tire etc in any little cowtown, where they wouldn't be cool enough yet to have 700c. A 5 speed rear is slightly stronger and you're less likely to break axles. With a triple in front, it was seen a sufficient number of gears.
You've got plenty of braze ons!
Top tube, shifters, BB cable guide, fenders, rack eyelets, and even braze ons for a water bottle! 
I had the Univega version of this frame, exact same color and year, so this one brings back some memories. I would have liked to have braze ons for a second bottle too, and I mounted a second cage with clips. At the time the seat tube was where you were expected to put the frame pump. I converted that bike to 700c and respaced the frame to 126 pretty much right away. This also was typical for the time.

It originally came with bar end shifters but I switched them out and used them on my Burley tandem.
I won't deny that it shifted a lot better with its original XC Sport triple pulley RD mated to the barcon shifters.

I picked up an '81 for my wife a couple years back. I swapped from 27" to 700c, and it was challenging to find front cantis that would work. It's a smaller sized bike, and other years and sizes might be different, but I'm thinking there's a chance that won't work without a torch.

I got the bike up and running yesterday.
I put on new tires and tubes, adjusted, lubed and tightened everything up.
It is now rideable and I am happy that it isn’t to big for me or my son to ride.
We still have a lot is work to do to it but it is one step closer.
