Check this out, the car on the bottom I think is the same wagon, maybe this old wagon pictured here founds its final home in this wrecking yard. [url]http://www.oldride.com/community/galleries/982885683.html[/url]
The empty space behind the rear wheel is the "door" behind which the spare tire was kept (only on 4 dr wagons). This one had the optional bumpers too. Rocker panels always disappeared.
We had a 56 Chrysler wagon at that time and the little urchin hanging out the back window was about my age. We were in Massachusetts and the Chrysler was also a rust bucket. I'm in Colorado now, much friendlier climate for old iron.
