Mine came out of Tampa, Fl. Dave Koorey's Street Rods. He's no longer in business but he made decent but inexpensive bodies for 10 years or more before his shop burned down in the late 90's. I bought mine in 93. They sold brand new for $3600. No interior framing but the doors and trunk came pre-hinged and latches installed. Also came with Impala electric window mechanisms installed. They were available with or without a frame. Mine came without, so I built my frame from a couple bare rails from American Stamping.
