Sure, I got the tension pulley and the guide pulley right.
I always thought there was a narrowing of cluster spacing between five-speed and seven-speed with the intermediate six-speeds either using the five-speed spacing or the seven-speed spacing (ultra-six). I have the five-speed and seven-speed clusters in front of me and the spacing on the seven is about 0.4mm narrower between cogs.
