I'm afraid that there are no known substitutes for this operator. You may be able to use something like our 39-315 and 39-316, but you'd have to alter the sill to accept the new style base. This would involve cutting the hole where it installs and redrilling new holes. You would also theoretically need new brackets like our 39-545 and 39-546. Please understand that this is an educated guess. There is no guarantee that even my suggestions will replace your originals. I'm sorry that we cannot offer a better match. |
