Hello,

We do not carry an operator like yours with a 14" arm but I would recommend starting by comparing the specifications of the 39-013 to your assembly. Note that the arm measures 13-1/2" from the center of the gear as shown below. If it's a match, we also offer the 39-014 opposite-handed version. 

Dimensions for 39-013

We also offer the 36-048 hinge set with a 10" base. Take a look and see how the specifications shown on our product pages compare to yours. Thank you!
