Many thanks Tom. I did ID the opener (39-171) and placed my order on line. I tend to need a lot of closer repair parts so I will be back again! Thanks Mike

We are looking for an interchangeable part for #30905 we need the right and left, is it possible to have a quote provided to us and what shipping is?

I'm afraid that number alone is not enough to make a recommendation. It's associated with many different operators, including the two I recommended for the customer above back in 2012. Have you reviewed these parts yet? If not, I suggest starting there. We have detailed pictures and dimensions that you can use as a reference.
