sliding door locking lever has broken off

This sliding door was installed in 1978. The locking lever has broken off. I didn't see a replacement lever on your website. The picture ending in 184144 shows the handle attachment screws. The picture ending in 184151 shows the broken off lock lever. The picture ending in 184138 shows the lock attachment point on the frame. The picture ending in 184141 shows the latch assembly. If you cannot advise which lever might work, I would also consider purchasing a new assembly to repair this door.
