2 1/16 center of screw to center of screw. 11/16 from rear of lock to front center of screw. Please give me a part number. Thanks

Thanks for posting! This window lock reminds me of the 90-278 Lock & Keeper. To determine if these are the right fit, carefully look over the dimensions below and compare them.

This lock does not have alignment lugs like the existing lock but I do believe it should work fine for the repairs.
