Hello. I agree that the 39-056 is similar to your original operator. We also carry the 39-056 Crossly crank with similar style and dimensions to yours. The length of the link arm can normally be compensated by the play in the linkage that these box operators tend to have but the hole in the link arm for the shoulder screw does need to be precise. Take a look and let us know if you have any other questions. |
