Hey,
When I purchased my 240sx convertible, the owner told me It will need the drain hoses re-attached. He just welded up the rear quarters before selling me the car, he did an excellent job with it. When selling the car he told me that if I don't re-attach these drain hoses that the rust will appear again and eventually rot the fenders.
I've done some research, and looked through my service manual and I couldn't really find any mention of these hoses.
Anyone have insight on this?
