Can anyone identify these door panels??

[jcash1995]

I just purchased my new house and it came with a body shop that's been out of business for the last year. I found a lot of parts still neatly packaged in their original boxes, stacked beside the paint booth. All of the new parts are neatly labeled, but some of the old parts have nothing on them. I've been able to identify most everything except these door panels.







Any ideas??
