Old sliding window sash lock

Hi I need to find a replacement part for the window sash lock. Width between screws are 2-1/4" standard. However, I will need something close to 1mm in order for the extruding lock portion to engage with the window. Most common one I found are just half the way reaching the window frame. I found the sash lock with shifting screw hole may work but not yet verified.

Secondly I will need to find the "groove finder & lock", sorry I'm not sure how to name these correctly. It's currently not sitting inside the groove so when first it's hard to slide and second the window will tilt and fall off because of it. The width of the screw is 2-1/2" and the groove sits between 12 - 21mm. Please see the picture for details.

Please see if there's any dimension needed. Thanks in advance!

Hello,

Your first photo shows the top tilt latch on the wrong side of the window. I'd recommend swapping your two top tilt latches so that the curved part of the tooth sits against the window balance. By doing that, you close the gap between the top sash and bottom sash. 

The locking tongue of the 90-005 extends 7/16", while the 90-075 lock extends 1/2". Unfortunately, it comes in bronze. Using an offset mounting lock would not work because it would bring the housing over the sash and it might hit the top sash. Take a look and see what you think.
