This is awesome. It wouldn't be allowed at my house! http://mansfield.craigslist.org/cto/2733234074.html
Looks like the reason this one survived is it only received mild work. Rather than having the body "stretched" this one is intact with just commercial glass and corresponding roof.
Flxette models used factory frame. (No, thats not a typo!) Premier models had the stretched chassis and sheetmetal.
I once traded 2 packs of eckrich smoked sausage and a 12 inch black and white tv for a 1963 cadillac hearse. My wife didnt let me keep it either.
