Thanks for your post! I believe you have the 39-253LB Encore Dual Arm Operator. It uses the 39-529 Truth Hardware Track Slider, which slides in the 39-528 track. To confirm that this is the correct replacement match, carefully look over the dimensions below and compare them.

The opposite version can be found tagged below this thread, along with the compatible hardware and accessories.
