Amy,
Sad to say that whoever is working on your car should have taken photos of everything prior to removing anything...that way you'd have a record.
I'm sure your car had much of what it needed prior to removal; even if the inner fenders were replaced, were your various wiring looms just flopping about in the engine bay?
There are a few folks here that have pretty straight 230SLs and can hopefully supply some photos. Most of these clips are still available from either Classic Center, Authentic Classics or others, so replacing yours shouldn't be an issue.
