Number of blades in final stage of LEAP turbine

Oddly specific question I know but would anyone be able to tell me (or provide a reference for) the number of turbine blades on the final stage of the LEAP-1A, which has 7 low px turbine stages; and the LEAP-1B, which has 5 of them - so I’m after the 7th and 5th stage respectively. I understand they’ve different amounts, presumably due to differing thrust ratings and engine sizes but I’ve drawn a blank trying to find dimensions of these things or the number of blades. Any bright ideas?
