Roto casement operator

A home owner from Home says:
Good morning. Attached pleas find pictures of my Roto casement single arm operator 7-1/2". I can not find it on your web site so my question is do you?
Question 1) If you do not carry a 7-1/2" operator can I use the old arm on a new operator such as a 9-1/2" one such as a 39-430?
Thank you in advance

Thank you again for your continued patience. I know it's been a long wait, but we finally tracked down a 7-1/2" version of the 39-430 that I think will work for you. Please give us a little more time to have it made up and I'll let you know when it is available.
