Hello, thank you for posting,
To further review, are you able to provide the distance between the installation holes from center to center of the handle? Please also confirm if the thumb lever is centered or offset on the handle. From there we can compare to determine the best replacement option. Thank you!
You will need to measure the distance between the installation holes from center to center as shown below.
If they measure 3-15/16", please review the 82-030A handle set with a centered locking thumb lever placement or the 82-030B with an offset thumb lever. Unfortunately I cannot confirm from the picture which style you have. The original handle set will need to be removed to confirm the placement of the lever on the door.
If the dimensions are not matching up, please let me know!
