I think your 39-253L will replace my Traco crank

I am in need of a replacement crank mechanism for a Traco casement/egress window also. I have 2 of these windows but only one of them "sticks" in the closed position and the gears have stripped over the years (~12) such that the window cannot crank shut. Based on the pictures on your website (awesome, by the way!) I need a 39-253L whereas the window with the 39-253R seems to be OK. Not sure if this is a lefty-righty issue or just plain dumb luck (one works properly, one does not). I am going to order a 39-253L and install it myself.
