Face Mount Keeper ID

That is similar to our 90-169, but it's clearly a different size. Before I recommend anything, can you tell me the distance between the two screw holes, center-to-center? I'm afraid that I can't tell what it is with just a ruler held up to the part. I would like for you to measure it as carefully as you can and tell me what it is.

Would it also be possible to see an undamaged version? 

Thanks, let us know! We'll start trying to find a keeper that matches that measurement in the meantime.

Can you confirm that measurement? We don't have anything with a hole center to hole center distance that's that small. 

The best match we have in our inventory is our 90-257, which has a hole center to hole center spacing of 7/16". Could this be a better match?
