Johnnyrod,
Was at CARS INC. open house last weekend they had a new full 1962 drivers side quarter hanging on the wall. Their catalog shows both right & left for under $400 each. May want to check them out if nothing comes up.
The other question that comes to mind is how is the reminder of rear quarter area? I need rear quarters on my 60 Elcamino but I also need to replace everything else behind the skins. Al of the rear wheel house and other areas are shot. No one reproduces those parts and I have scoured the local bone yards for a suitable donor vehicle. I have located a 59 two door that should do. lots of work ahead .
