Duster lower rear quarter patch panels, who makes them?

I don't know if they specifically make patches for the front of the quarter. For that you may have to source it from a parts car because that section didn't rust out as badly as the rear section so they should be plentiful.

Always go with AMD if they stock it. By far the best sheet metal. Goodmark and Sherman are hit and miss. Mainly with body lines. The body lines just aren't stamped as crisp as AMDs are. They also don't seem to flange some panels that came flanged from the factory.
