Finding a Y-block valley pan in an auto-salvage yard will be like searching for the proverbial "needle in a haystack." Unless you know of a yard that specializes in classic/antique cars, they don't hold onto cars for very long. What isn't stripped and sold, goes to the crusher. I see Y-block valley pans on Craigslist and ebay from time to time. Also check this forum's "For Sale" section, as well as on y-blocksforever.com.
