Hello! I plugged your stamp numbers into our database and found that it was associated with our 39-031 and 39-032 operators. Assuming this is what you're referring to, you'll need the 39-107 cover and 39-114L handle. Just make sure to compare your dimensions to ours and ensure everything matches up.
