I'm afraid we haven't been able to find a version of the 39-171 and 39-172 with arms in that size. Could you have our 39-317 and 39-318 instead? The main difference is the size and style of the link arm; for the 39-317 and 39-318, the link arm is 3-1/2" from hole-to-hole, and it is straight instead of offset.
If you are confident you have the offset arm of the 39-171 and 39-172, you can swap the arms by drilling them out, then installing the old arm on the new operator with the 62-014 rivet. |
