Hello, I’m looking to replace the latch housing for my Thule Adventurer circa 2000 that broke. I can only seem to find the locks, but need the whole plastic piece. Any tips? Photos attached.

Thanks for the pictures! Sorry to say but Thule stopped making replacement parts for their Adventurer cargo boxes quite awhile ago. The only Thule parts that still work with it are the lock cores like item # TH450200.
