Looking for the much less bulky sliding door latch

Our thumb latch broke and our contractor replaced it with a thumb latch that points up and to the right. The contractor threw the old latch away. THE ORIGINAL LATCH WAS A MUCH LESS BULKY AND POINTED DOWN.

If it helps, below is what is etched on the bottom of the pane of glass AS BEST AS I CAN READ IT:

TUF-FLEX 5/32" d
TEMPERD SAFETY GLASS
ANSI Z97.1 1975
SGCC 546
16CFR201-1.11

SGCC84.5

Tom: I am an idiot, my wife reminded me that we had an identical door in the house, so I took pictures of the latch hardware that I am looking for and the 2 pics are attached.......thanx for your help.....Tim

Tom,
thanx for your help.The problem with the 82-043 is unlike the old unit, it faces up and swings to the right. This causes the thumb latch to hit the door jamb and not service correctly. The old one, as you see faced down. If you tell me the 82-043 and the 82-316 can be installed upside down, I will certainly order them. thanx again....tim

tom:

thanx to all your help, i am about to order the 82-043 and the 82-316 from you. I am ordering the 82-316
because the lock is mounted on the outside of the door and as you look at the door from the outside the lock is on the left side. If this is all correct, I will go ahead with my order...Thanx again..Tim
