On eBay, use the search function to locate item #310770277519.
The item listed is a reproduction of the original Ford over-the-parts-counter '56 Power Pack valley pan. Some say that these were also used on early '57 Ford 'E' production vehicles.
The quality is excellent, actually better than Ford's. Ford's early flat steel valley pans were a little crude as to the positioning of the oil fill tube in relation to the corner edge of the pan.
______________________
IF you prefer the more recognized-as-being '57 'E' valley pan, this same vendor modifies original vintage valley pans to be 'pass-for-original' 'E' pans. Workmanship is THE best.
Use the question option at the end of the eBay listing to contact him regarding the reproduction '57 'E' valley pan.
Hope this helps.
