I kept one side on, but since I did them 5 years ago, they are only reassembled as good as I could then!
Mostly concerned about how the adjusting spring goes into the shoe. It can be done 2 different ways, but one is much tighter than the other.
Mine a 1989.

 

Turn the spring over.

 

I ended up doing them like the first photo. Down to final adjustment, no test drive yet.
BTW: I agree, no Grandson dog collar!
