I've been trying to find this replacement lock for my windows. All the handles are starting to break off. You have two similar models (90-072 and 90-287) but the dimensions are not quite right. I've attached a photo of the current lock with it's dimensions. The only identifiable marking on it is on the underside tab. It says 11R-1. I appreciate your help in locating a replacement. The Home Depot and Lowe's replacements do not have the off-set mounting holes.
