Hi There - thanks for the reply. Our arm is exactly 14 " as is yours. Our operator measures 4.5" across from hole to hole where yours is 3 23/32. The left side measures 3/4 inch as does yours but the right side measures 1.5" where yours is 1 1/16.
Do most people just drill new holes? I am not sure when the operator was installed. The house was built in 1974 but the previous owner replaced the windows in the 90's we've been told.
Thanks for your help.

Hey, Kim. Well, Andersen themselves have stated that this replacement operator may not be exactly the same as the operator being replaced. You may have to drill new holes, but as long as they're not overlapping there shouldn't be a problem.
