Hello! I have personally replaced the GU operator more than a few times using the 39-316, along with the related parts we mention in our video. I find that it works very well as a replacement despite the differences in arm size. Just note that you will definitely have to redrill your installation holes. Just make sure to take your time, since you want to make sure its oriented in the right position for optimal function. |
