Truth Casement Operator

Looking for a replacement for this operator for a 22" casement window. The baseplate has 3 screws aligned DIAGONALLY on each side of the arm. The distance between the 2 outside screws on the sill plate is 3 inches, center to center. The length of the swivel arm is 5 inches.

It seems similar to the Ellipse dyad operator, but the sill plate is different.

Hello! Start with our 39-172 and 39-171 operators. These are the closest I can find. Just make sure the dimensions all match up. The plate is a little different, but I don't see how it'd be so different it would render them incompatible. The size and style of the arm linkage is more important.
