I'm assuming the 950 and 955 have the same belts.
I fairly confident that the two smaller belts are:
SCX4.3
SCY4.2
The main belt I ordered for a 950 back in 2020 was an FRX10.5 but everything I've been reading has the length at 10" and I can't remember if the 10.5 worked or not.
Can someone let me know if the correct length is 10 or 10.5?
