All is not as well as I thought. In the earlier entry the brake shoes were lined up one hole too high. My fault for misreading the instructions. I also had tried to attach the brake rigging too high. 
 

A golden rule that I have yet to learn fully is that if a part doesn’t fit without force, you may have made an error. These kits are good, not many errors at all, so if it don’t fit, you’ve probably done it wrong!

Take 2 seems to be hanging together well.
