Thank you for your question on the Delta Victorian Tank Lever.
I am more than happy to assist you today. All of our universal tank levers are currently being manufactured with the plastic trip lever assembly at this time, though there may be some older models available depending on whether the store where you purchase your assembly from still has older stock available.
