The base that mounts to the sill is 2 1/8" front to back, 5" left to right. The straight arm is 9 1/2" long. The curved arm that extends to the right is approximately 8" long. Thank you

Hello,
Depending on the length of the shorter link arm, you could have either the EntryGard 39-032 or Caradco 39-156 operator. Take a look and see how the dimensions compare to yours. Thanks for posting!
