1965/66 Ford 390 Engine Original Valve Covers. These were in a box of parts that came with a 1967 289 Mustang. Obviously, they are not from a 67 small block mustang. My research, primarily asking for identification help on Vintage Mustang Forum and looking on Ebay, indicates they are from a 65-66 ford 390. I got what I needed off of the parts car, so I don't want a fortune for these. $40 plus shipping will be fine.
