Currently I have purchased the fenders from another lister, the rocker panels from the Mercedes Benz Dealer (at a cost of $600 dollars). And the rear quarters are currently getting cut off another 450SEL at a yard 100 miles away from where i live.

As you own a 280SE, you can still get aftermarket rocker panels at less then $100 dollars each. You can also get wheelarch repair sections.

Once place to find these parts is http://www.rustrepair.com. Good luck and post some pictures. We would love to see the progress your making.
