I have a "new" 1978 300D. No rust (it was an AZ and CA car for almosta all its life). Taking preventive action, I have decided to clear out the drains which might cause rust for me (as I live in the rainy Pacific NW).

I have found the drains under the hood hinges, and one under the fuse box. I have cleaned out a TON of debris. But I have NOT been able to find a drain under the battery on the firewall. In fact, I cannot reach anything under the batter. Am I supposed to take out the battery?? Could someone post a picture or diagram which would help me understand the location of the drain?

My sunroof will not open (broken!), so I cannot access the sunroof water drains. Is there another way to clean them?

And last, the channels above the doors are filled with pine needles and debris. I have tried needle-nose pliers, and jet spraying with water. I am wondering if there is a great way to clear these out from above or below or wherever the access to this drain might be.

It isn't raining these days in WA, so it's an ideal time to get prep done.

Thanks for any help!! I appreciate this forum!!
