Note: offset top hole. Will 39-056 fit?

Robert, thank you for submitting your inquiry to our discussion board.

Based on the pictures you sent in, we believe the 39-432 might be a better option for you.

Please compare the dimensions to your current operator and let us know if you think this will work for you.

I agree that the 39-432 isn't your best option due to the fact that it lacks the offset top hole. The 39-056 is closer, but I just ran in back and took one out of stock to look at. While the top hole is indeed offset, it looks to skew closer to the center, by my eye.

Truth be told, we haven't been able to find a more exact match to your original part. I suspect that it may not be made anymore. Would you happen to know who manufactured your window? That may allow us to at least confirm that we can't get a closer match. 

Another concern is the shoulder screw at the end of the link arm. The 39-056 lacks the sleeve that yours has, though that may not come into play. The 39-056 is designed to be used with a 33-067 shoulder screw.

Let me know your thoughts, or if you had any other questions.

That top to bottom hole may be an issue. 1/16" is nothing to sneeze at, and its a narrow enough difference that drilling a new screw hole could result in overlap with the old hole, which is no good. I would double-check to make sure that you're measuring from the center of each hole, not their edges, just to be 110% sure.

As for the offset of the top hole, I thought I'd go back again and give you a more precise measurement. I used the photo you submitted as a reference. Hopefully this clears things up for you.

That's great news! Yes, 0.372" is the same dimension on the 39-056. I was worried that ours was different, but if they match up then that's one problem solved.

The only issue remaining is the distance between the top and bottom hole. There isn't much you can do; enlarging one of the holes, as you mentioned, is probably your best bet, though of course that comes with a few risks. 1/16" isn't insignificant, so you'll be cutting it close.

That said, I think that our 39-056 is our best option. I cannot guarantee it will work, but I think with a little patience and careful drilling it could be possible.
