Hello, Your operator is a very old style that hasn't been made in years. You may be able to use a more modern part like our 39-027E and 39-028E as substitutes but I cannot guarantee that they will work. If they do, it would require some adaptation of the sill and sill trim due to the differences in the shape of the operator bases. As for your lock, it looks like it may be an older version of our 38-097 and 38-098. Your specific model has not been made in many years but the newer parts work just as well, regardless of the number of screw holes. The only catch is that you will need to replace the old keepers with the newer 38-079. Thake a look and see what you think. |
