There is another issue, the direction of the twist of the rope. If the rope twists the wrong way for the direction the winch turns, you will never get it to lay smoothly. The TM that discusses rigging tells how to make sure you use the right twist rope on the winch.If you feed the winch with the wire rope within about 10 degrees or so of straight on, a level winder shouldn't be needed anyhow. My 5-ton (m656/xm757 series) doesn't have one since it's mounted upside down and none was specifically made for it.
Never seen one for the deuce winch...
