Hello,

Take a look at the video below that will help you choose between the 39-253LB & 39-253RB , or the 39-438B & 39-439B Encore operators. 

If you need new hinges as well, you can start by comparing the 36-048 or 36-049 to your assembly, depending on the size of your original assembly. Thank you!

Please see photos. Looks like it uses a one hole slide. See photo of the bottom of part the front cover that hides the gears is riveted from the bottom can I get a whole assembly with the cover installed? Also it hinges from the right

It looks like you may have the 39-529 track slider used with the 39-253LB and 39-253RB but I'd recommend detaching it from the track to confirm that it is an exact match. 

If so, you can use the 39-375 and 39-376 handle and cover kits for your replacement operators.
