KMC x8.93 is listed as a 8 speed but I will buy it as it's the same. I don't know why they list the chains as 7 speed or 8 when it's the same (if 7.3)?

1/2” X 3/32” - 116 Links
pin length 7,3 mm
The width of and spacing between 7- and 8-speed sprockets are really close, almost identical. Unlike with most other changes, the move from 7 to 8 didn't come from cramming one more gear into the same space, an extra gear's width was added to the freehub body and cassette. So the chains barely needed to change, and lots of us use "8-speed" chains on our 7-speed systems, like the SRAM PC-850 and 870 that Chas mentioned earlier. Works great, and makes finding a chain much easier.
