Update on the stink removal. I got rid of it by cleaning the area with a HD detergent called tough stuff, locally available. Thoroughly rinsed the area with sponge and fresh water, then used solution of beach and water, and again rinsed it. Dried the area with the heat gun, and ran the ozone generator aimed directly at the area overnight. In the am the rear quarter smelled clean, but there was still a faint stink in the car, likely in the upholstery. I will get that by running the ozone generator located up high, (ozone is heavier than air), with a fan to circulate it in the car.
I scribed a template of the rear quarters curvature and made a bulkhead plate to block off the rear quarter from the trunk area. Eventually I will sound proof the bulkhead, and clad it with metal. Still have to figure out how to block off the upper areas from the trunk. see photo of rear quarter with lower bulkhead in place.
