Weaver base for Henry 45/70?

Had a customer come in the store last night looking for a Weaver base for a Henry 45/70 rifle. The Weaver chart does not list Henry rifles. The Weaver websight does not list henry Rifles and Henry was closed for the weekend so I could not call them. Does anyone have an updated Weaver base chart that lists Henry lever actions? It should be a one piece with four holes.
