I have Marshall Windows. The part I need is where the latch lock screws into the window. The part on the window has fallen apart and crumbles therefore I can no longer screw the keeper onto anything. The sash locks just locksunder the Top window But I am no longer able to screw the entire lock because the piece that the screw tightens into the part is crumbled
There is no way to mount the sash lock. Can you help me?
