That is rough! Make sure you make templates of the fender trim so you can transfer them on to your non trimmed fenders. Save the seat riser if you decide to cut it behind the front doors. The front door stainless is good to keep and may work on your other panel if it's pre-51 and with a little work if it's 51 or newer. Save the gas tank and mount. The rear door stainless is unique to the deluxe panels although can be used on the suburban too. The Bucket seats look like they are from a 1964 Pontiac or at least a GM car of that vintage.
Looks like you have a 1955-62 chevrolet 235 car engine, possibly with hydraulic lifters, would need more information than what I can see from the picture. What is the casting number and the stamped number on the engine? What is the number on the body tag located on the drivers side pillar? Save the radio delete panel and buttons too.
Patch panels made from the bottom of the front doors will replace the lower body area behind the front door and in front of the rear fender.
Good luck and keep posting pictures.
