This part is only about a 1/4 inch wide and 2 inches center to center on the screw holes and 2-9/16 overall length I bought item number 90-278 but it was to wide and would not close right Thanks Brian

Hello,
Take a look at the 90-177 keeper, which works with the 90-077C lock with 2-1/16" screw holes, is 2-9/16" wide but 5/16" thick. Review the specifications to see if you think this could fit it on your sash.
