Hello, thank you for posting,

Please start by reviewing the style of the 39-315 and 39-316 operators. Compare the dimensions below to confirm a good fit! If you see any discrepancies in the style, please let me know! For a new handle, see the 39-114L

Let us know if you have any additional questions.
