Guess what, you're wrong, not all chains are 3/32'' inside width check a 9speed chain lately?
Between the outer plates: 1/4"
Between the inside plates: 1/8"
But yeah there is only a hair of a difference between a 7 and an 8. After having awhile to think the chain reccomendations I'd just go with a BMX chain. When shimano developed the 9 speed system, they couldn't get the width of an 8 speed to have the proper clearance, so they had to make a narrower chain to work with a 9 speed system.
