RD350 YPVS CARB RUBBERS wanted

[MWR]

Can someone steer me to what carb rubbers I use for the big body -32mm -Mikunis I am trying to install on my bike, the OD is 40mm of the carb, I have found some in the states from drug money they look like a stock part off another Yamaha?
plenty of stock ones to suit the 28mm stock carbs in Alliexpress?

thanks , Murray
