Need help replacing my cracked SGHD-3-A-1 handle

We unfortunately don't sell this exact handle, but it looks like a fairly typical sliding glass door part. Something like our 82-030 may work perfectly well for you.

Before you buy anything, though, I'd like a few more details so that I can be more confident in that suggestion. Please start by giving me the distance between the two installation holes, center-to-center. It should be 3-15/16" but I want to be 100% sure.

Please also show me a clear picture of the mortise lock in the door. We need to be sure that our 82-030 is compatible, otherwise it won't be worth considering.
