Olympia SF 33 shift alignment off and keys hard to press after shiping

I recently received an Olympia SF 33 typewriter that was professionally cleaned before shipping, but it has significant shift alignment and typing issues.

Symptoms:

1. Shift Alignment: Normal lowercase is fine, but the Shift Lock makes the carriage go drastically too high, causing the top half of uppercase letters to be faint or cut off.
2. Missing Latch: I cannot find the metal hook/latch that usually holds the shift mechanism in place. I'm not sure if I'm just not seeing it, or if it's missing entirely.
3. Heavy Keys: The keys require significant force to press.

I suspect shipping damage to the carriage stops or linkage. How can I adjust the "on-motion" stops to fix the over-travel, and what should the missing shift lock latch look like? I can provide photos if needed.

Thank you!
