Hey all, working on a 300dt for my friend. Already fixed leaking oil cooler line by cutting in half and putting compression fitting on (see other post).

Two other issues:

won't start off key; will start off jumping starter block to battery just fine. Tried jumping the two purple wires for NSS. No go. Ignition key assembly?

2nd: under the front right control arm, there seems to be something missing. Is it important? He claims there is some kinda clunk from front end when driving. All the bushings for the front end were replaced by PO. This is the only part that seems out of place (see pics).

Thanks!
