Window crank replacement

These old fashioned operators unfortunately don't have a low profile option. Different color finishes are also not viable in most cases, since most manufacturers aren't really interested in making them anymore. They just aren't as common as they used to be so your options are unfortunately limited. I know you want them to match your windows but that is probably not going to be an option unless you want to paint them yourself.

All that aside, I do agree that the 39-056 is our best option. The difference in link arm size isn't really a big deal since there's a certain measure of play in the linkage. I'm more concerned with the size of the link arm hole and the installation hole pattern. You'll want to ensure that those are the same.
