hello,
I have a 21-speed Dyno with mountain bike style tires (~2").
In order to remove the rear wheel, I released the cable from the rear
left brake shoe. There was a plastic spacer/tensioner that broke when I
rotated the shoe arm out. This plastic piece fits over the spring.
Is this part commonly sold? Can I buy one at most bike shops?
It seems that to replace it, I have to remove the pin with an Allen
wrench.
For now, I'm getting along after reinserting half of the spacer, then
rotating the brake shoe arm back into position.

Nashbar's got a full set of rebranded Tektro cantis for $20 if you're
in the states and don't want to mess around with sourcing the part:

Apologies for self-responding:
the model/part number is
br-ct90-m
Once I googled this part number I found a post saying that Shimano issued
a recall notice for it, due to the exact problem that I'm having.

Oh, I get it! The grey plastic spring cover on that model is not
decorative, it holds one end of the spring.
Stop at any competent LBS where they will have a Shimano-supplied kit
for those with three springs and three covers to rebuild any and all
cantilevers of that series (with parts left over).
Replace both sides as the other one is either cracked or about to fail.
