Hello All:
In the throws of restoring this great car. I have encountered surface rust..............not a problem aka BONDO . I am now at the rear quarter panels...............man!

The left (passenger side) is DOA. The wells in the trunk are compeletly gone on both sides.............wheel well on drivers side is intact. My question is.....what was the construction material of the wells in the trunk. It seems to have some type of insulation with sheetmetal and some type of coating. Does anyone have insight into the correct fix. I am going to definitely have to replace the 1/4 and rocker on the passenger side. Does anyone know of a reasonable supplier?? Thanks for any information you can provide.
Best Regards,
Scott 78 280 SE/CE
